Description
Fremgangsmåte til fremstilling av blandede sekundære aralkyl-aralyl-oksy-alkyl-aminer eller disses salter. Process for the preparation of mixed secondary aralkyl-arallyl-oxy-alkyl-amines or their salts.
Det har allerede vært foreslått å fremstille forbindelser med den generelle formel It has already been proposed to prepare compounds of the general formula
eller disses salter. I denne formel betyr R3 en alkylengruppe med 2 til 6 kullstoffatomer, R4 en alkylengruppe med 2 til 6 kullstoffatomer, hvor et av vannstoffatomene kan være erstattet med en hydroksylgruppe og YH og Y4 vannstoff eller minst en hydroksylgruppe eller en foretret eller en forestret hydroksylgruppe. Ifølge dette forslag kan disse forbindelser, som er i be-sittelse av gode farmakologiske egenskaper, fremstilles ved å la en forbindelse med den generelle formel reagere med en forbindelse med den generelle formel or their salts. In this formula, R3 means an alkylene group with 2 to 6 carbon atoms, R4 an alkylene group with 2 to 6 carbon atoms, where one of the hydrogen atoms may be replaced by a hydroxyl group and YH and Y4 hydrogen or at least one hydroxyl group or an etherified or an esterified hydroxyl group. According to this proposal, these compounds, which possess good pharmacological properties, can be prepared by allowing a compound of the general formula to react with a compound of the general formula
eller et salt herav under fraskilling av halogenvannstoffsyre. or a salt thereof under separation of hydrohalic acid.
I disse formler har Y3, R3, R4 og Y4 samme betydning som ovenfor, dog kan R4 også være en alkylengruppe med 2 til 6 kullstoffatomer, hvor et dobbeltbundet sur-stoff-atom er til stede ved et av kullstoff-atomene, mens Hig er et halogenatom, fortrinnsvis et klor- eller bromatom. Hvis R4 inneholder en ketogruppe, reduseres denne til en hydroksylgruppe etter avsluttet kob-lingsreaksjon mellom forbindelsene med formlene (II) og (III). Denne reduksjon kan foretas med vannstoff i nærvær av eh katalysator, f. eks. finfordelt nikkel, platina eller palladium, etter Meerwein-Ponndorfs metode eller med aluminium-amalgam, litium-aluminiumhydrid eller natrium-borhydrid. In these formulas, Y3, R3, R4 and Y4 have the same meaning as above, however R4 can also be an alkylene group with 2 to 6 carbon atoms, where a double-bonded oxygen atom is present at one of the carbon atoms, while Hig is a halogen atom, preferably a chlorine or bromine atom. If R4 contains a keto group, this is reduced to a hydroxyl group after completion of the coupling reaction between the compounds with the formulas (II) and (III). This reduction can be carried out with hydrogen in the presence of a catalyst, e.g. finely divided nickel, platinum or palladium, according to the Meerwein-Ponndorf method or with aluminum amalgam, lithium aluminum hydride or sodium borohydride.
Disse forbindelser kan også'fremstilles ved hydrering av en fenoksyalkanon i nærvær av ekvivalente mengder av et fenyl-alkylamin resp. fenylalkoholamin eller et fenylalkanonamin. These compounds can also be prepared by hydrogenating a phenoxyalkanone in the presence of equivalent amounts of a phenyl-alkylamine resp. phenylalcoholamine or a phenylalkanonamine.
Man har funnet at man kan fremstille en forbindelse med den eenerelle formel It has been found that a compound with the general formula can be prepared
eller dennes salter ved å la en forbindelse med den generelle formel or its salts by adding a compound of the general formula
i in

eller et salt herav, hvor Yj og Y2 er et vann- or a salt thereof, where Yj and Y2 are a water
stoffatom, en hydroksylgruppe eller en foretret eller forestret hydroksylgruppe, R'] en alkylgruppe med 2 til 6 kullstoffatomer, hvor et kullstoffatom bærer et dobbeltbundet surstoffatom mens en hydroksylgruppe eller et dobbeltbundet surstoffatom kan være bundet til et av de andre kullstoffatomer, R, er en alkylengruppe med samme kullstoff skjelett som R', gruppen, dog således at kullstoffatomet, som i den tilsvarende gruppen R^ har et dobbeltbundet surstoffatom, er bundet til kvelstoffatomet i gruppen R,, mens et av de andre kullstoffatomer i gruppen R3 kan bære en hydroksylgruppe, d.v.s. det kullstoffatom, som i den tilsvarende gruppe R, har en hydroksylgruppe eller et dobbeltbundet surstoffatom, og R2 er en alkylengruppe med 2 til 6 kullstoffatomer, hvoretter reaksjonsproduktet hydreres, hvorpå det eventuelt ennå tilstedeværende dobbeltbundne surstoffatom reduseres til en hydroksylgruppe, og om det ønskes forestrede eller foretrede grupper Y, og eller Y2 omdannes til tilsvarende hydroksylgrupper. substance atom, a hydroxyl group or an etherified or esterified hydroxyl group, R'] an alkyl group with 2 to 6 carbon atoms, where a carbon atom carries a double-bonded oxygen atom while a hydroxyl group or a double-bonded oxygen atom can be bonded to one of the other carbon atoms, R, is a alkylene group with the same carbon skeleton as R', the group, however such that the carbon atom, which in the corresponding group R^ has a double-bonded oxygen atom, is bound to the nitrogen atom in the group R,, while one of the other carbon atoms in the group R3 can carry a hydroxyl group , i.e. the carbon atom, as in the corresponding group R, has a hydroxyl group or a double-bonded oxygen atom, and R2 is an alkylene group with 2 to 6 carbon atoms, after which the reaction product is hydrogenated, after which the possibly still present double-bonded oxygen atom is reduced to a hydroxyl group, and if desired esterified or etherified groups Y, and or Y2 are converted into corresponding hydroxyl groups.
De eventuelt i bensolkjernen tilstedeværende hydroksylgrupper kan være forestret enten i det ønskede sluttprodukt eller i utgangsstoffene V og VI, f. eks. med eddiksyre, propionsyre eller bensoesyre, eller de kan være foretret, f. eks. med bensylalkohol eller etanol. Særlig kan bensyl- og acetylgruppen om man vil igjen lett avspaltes ved katalytisk hydrering under innvirkning av finfordelt platina, palladium etter Raney-nikkel resp. ved reduksjon, f. eks. med litium-aluminiumhydrid. The hydroxyl groups possibly present in the benzene nucleus can be esterified either in the desired end product or in the starting substances V and VI, e.g. with acetic acid, propionic acid or benzoic acid, or they may be etherified, e.g. with benzyl alcohol or ethanol. In particular, the benzyl and acetyl group can, if desired, be easily split off by catalytic hydrogenation under the influence of finely divided platinum, palladium after Raney nickel or by reduction, e.g. with lithium aluminum hydride.
Porestrede hydroksylgrupper kan også med letthet omdannes til frie hydroksylgrupper ved forsåpning. Dette kan gjøres med fortynnede syrer eller alkoholisk saltsyre, svovelsyre eller en fortynnet, vandig eller alkoholisk oppløsning av kalium-, natrium- eller bariumhydroksyd. Avspaltes etergruppen med en syre, må man passe på at aryloksy-alkylgruppen ikke spaltes samtidig. Forsåpningen bør derfor ikke med en konsentrert syre og/eller ved en for høy temperatur. Fortrinnsvis arbeider man ved en syrekonsentrasjon mellom 0,1 og 2n og ved en temperatur av 15 til 60° C. Porous hydroxyl groups can also easily be converted into free hydroxyl groups by saponification. This can be done with dilute acids or alcoholic hydrochloric acid, sulfuric acid or a dilute aqueous or alcoholic solution of potassium, sodium or barium hydroxide. If the ether group is cleaved with an acid, care must be taken that the aryloxy-alkyl group is not cleaved at the same time. The saponification should therefore not be done with a concentrated acid and/or at too high a temperature. Preferably, you work at an acid concentration between 0.1 and 2n and at a temperature of 15 to 60°C.
Det skal også bemerkes at gruppene Y, og/eller Y2, hvis de er hydroksylgrupper It should also be noted that the groups Y, and/or Y2, if they are hydroxyl groups
(eller forestrede eller foretrede hydroksylgrupper), fortrinsvis er bundet i parastilling i bensolkjernen. (or esterified or etherified hydroxyl groups), are preferably bound in the para position in the benzol nucleus.
Ved de forskjellige mulige konfigura-sjoner av gruppen R^H er en gruppe med den generelle formel In the different possible configurations of the group R^H is a group with the general formula
fortrinsvis en gruppe med formelen preferably a group of the formula
særlig bemerkelsesverdig. particularly noteworthy.
I disse grupper er R(; og R7 en alkylengruppe med 1 til 5 kullstoffatomer resp. et vannstoffatom eller en alkylgruppe med 1 til 4 kullstoffatomer. Eksempler på disse grupper R,NH er In these groups, R(; and R7 are an alkylene group with 1 to 5 carbon atoms or a hydrogen atom or an alkyl group with 1 to 4 carbon atoms. Examples of these groups R,NH are
I disse grupper er alltid en hydroksylgruppe bundet til det venstre kullstoffatom. Det skal dog bemerkes at det ifølge oppfinnelsen også kan fremstilles forbindelser hvor denne hydroksylgruppe enten slett ikke er tilstede eller i stedet finnes i gruppen R,. Dog fremstilles fortrinsvis de forbindelser hvor en hydroksylgruppe er bundet til det venstre kullstoffatom. In these groups, a hydroxyl group is always attached to the left carbon atom. However, it should be noted that according to the invention it is also possible to prepare compounds where this hydroxyl group is either not present at all or is instead found in the group R,. However, those compounds where a hydroxyl group is bound to the left carbon atom are preferably produced.
Forbindelser hvor den nevnte gruppe R,NH er tilstede fås når man går ut fra de forbindelser med den generelle formel V, hvor gruppen - R, er: Compounds where the aforementioned group R,NH is present are obtained when starting from the compounds with the general formula V, where the group - R, is:
Reaksjonen mellom utgangsstoffene The reaction between the starting materials
(V og VI) kan eventuelt finne sted i fravær i av et oppløsningsmiddel, men isåfall bør reaksjonen foregå under oppvarmning, i f. eks. ved en temperatur av mellom 60 og i 150° C. (V and VI) can possibly take place in the absence of a solvent, but in that case the reaction should take place during heating, in e.g. at a temperature of between 60 and 150°C.
Forskjellige oppløsningsmidler kommer i betraktning, f. eks. lavere alifatiske alko-holer, som metanol, etanol, isopropylalko-hol, butanol eller isobutanol. Videre kan man også anvende alifatiske eller aromatiske etere, f. eks. dimetyl- eller dietyleter, diisopropyleter, fenetol og anisol. Man kan også anvende polare oppløsningsmid-ler, f. eks. eddiksyre. Foruten de ovenfor nevnte oppløsningsmidler, kan man også anvende et overskudd av en av de to reak-sjonskomponenter V eller VI som oppløs-ningsmiddel, iallfall når disse komponenter er flytende ved reaksjonstemperaturen. Selv om nærværet av vann i oppløsnings-midlet ikke hindrer dannelsen av reak-sjonsproduktene av forbindelsene V og VI, bør reaksjonen dog foretas i et medium, som høyst inneholder noen få prosent vann, da ellers hydrolyse av den sannsynligvis i mellomtrinnet dannede Schiffske base kan finne sted, så utbyttet av det ønskede produkt blir mindre. Different solvents come into consideration, e.g. lower aliphatic alcohols, such as methanol, ethanol, isopropyl alcohol, butanol or isobutanol. Furthermore, aliphatic or aromatic ethers can also be used, e.g. dimethyl or diethyl ether, diisopropyl ether, phenetol and anisole. You can also use polar solvents, e.g. acetic acid. In addition to the above-mentioned solvents, an excess of one of the two reaction components V or VI can also be used as a solvent, at least when these components are liquid at the reaction temperature. Although the presence of water in the solvent does not prevent the formation of the reaction products of the compounds V and VI, the reaction should however be carried out in a medium that contains at most a few percent water, as otherwise hydrolysis of the Schiff base probably formed in the intermediate step can take place, so the yield of the desired product is reduced.
Reaksjonen mellom forbindelsene V og VI krever intet nøyaktig bestemt pH-område. Dog anvendes vanligvis pH-områ-det mellom 4 og 11. The reaction between compounds V and VI does not require a precisely defined pH range. However, the pH range between 4 and 11 is usually used.
Hydreringen av reaksjonsproduktet mellom forbindelsene V og VI kan foretas med vannstoff i nærvær av en metallkata-lysator. Som sådan kommer f. eks. Raney-nikkel eller et finfordelt edelmetall, f. eks. platina eller palladium i betraktning. Hydrering med platina som katalysator kan foretas ved værelsetemperatur under nor-malt trykk. Anvendes Raney-nikkel eller palladium som katalysator kan et høyere trykk anbefales, f. eks. et trykk mellom 2 og 100 atm. Som regel foregår da reaksjonen under oppvarmning. Man anvender da en temperatur mellom 20 og 100° C. The hydrogenation of the reaction product between compounds V and VI can be carried out with hydrogen in the presence of a metal catalyst. As such, e.g. Raney nickel or a finely divided precious metal, e.g. platinum or palladium in consideration. Hydrogenation with platinum as a catalyst can be carried out at room temperature under normal pressure. If Raney nickel or palladium is used as catalyst, a higher pressure may be recommended, e.g. a pressure between 2 and 100 atm. As a rule, the reaction then takes place during heating. A temperature between 20 and 100° C is then used.
Hydreringen kan finne sted straks etter at reaksjonskomponentene V og VI er blandet med hverandre. Dette har den for-del at det rå koplingsprodukt ikke først må fraskilles eller renses så det heller ikke er fare for spaltning av reaksjonsproduktet. Hydreringen kan foretas både i surt og basisk miljø. Sterkt sure eller basiske for-hold må dog unngås. Fortrinsvis finner hydreringen sted ved en pH-verdi mellom 5 og 10. The hydrogenation can take place immediately after the reaction components V and VI have been mixed with each other. This has the advantage that the crude coupling product does not first have to be separated or purified, so there is also no risk of decomposition of the reaction product. The hydration can be carried out in both acidic and basic environments. However, strongly acidic or basic conditions must be avoided. Preferably, the hydration takes place at a pH value between 5 and 10.
Hydreringen av den Schiffske base, som sannsynligvis er tilstede i mellomtrinnet, foregår forholdsvis raskt og omtrent samtidig med eventuelt tilstedeværende med bensylalkohol foretrede hydroksylgrupper Y, og/eller Y2. Inneholder gruppen R4 en ketogruppe, så reduseres denne senere enn forbindelsenes V og VI koplingsprodukt. Det er således mulig å fraskille det dannede ketoamin og å redusere denne forbindelse til en aminoalkohol på annen måte. En slik reduksjon kan foretas på mange måter. Forbindelsene kan f. eks. reduseres med et alkalimetall og-en alifatisk alkohol, f. eks. natrium og etanol eller natrium og propyl-englykol. Man kan også foreta reduksjonen med et komplekst metallhydrid, som har to metallatomer, f. eks. natriumborhydrid eller litium-aluminiumhydrid. Foruten disse reduksjonsmidler kan man også bruke alu-miniumpropylat etter Meerwein-Pondorfs metode. The hydrogenation of the Schiff base, which is probably present in the intermediate step, takes place relatively quickly and approximately simultaneously with any hydroxyl groups Y, and/or Y2 etherified with benzyl alcohol. If the group R4 contains a keto group, this is reduced later than the coupling product of compounds V and VI. It is thus possible to separate the ketoamine formed and to reduce this compound to an amino alcohol in another way. Such a reduction can be carried out in many ways. The connections can e.g. is reduced with an alkali metal and an aliphatic alcohol, e.g. sodium and ethanol or sodium and propylene glycol. One can also carry out the reduction with a complex metal hydride, which has two metal atoms, e.g. sodium borohydride or lithium aluminum hydride. In addition to these reducing agents, aluminum propylate can also be used according to Meerwein-Pondorf's method.
Disse reduksjonsmetoder utføres vanligvis i et oppløsningsmiddel. For reduksjon med et alkalimetall og en alifatisk alkohol anvendes alkoholene selv eller om nødven-dig aromatiske eller alifatiske estere, f. eks. dietyleter, fenetol eller anisol som oppløs-ningsmiddel. Ved anvendelse av et komplekst metallhydrid som reduksjonsmiddel kommer særlig alifatiske eller sykliske etere, f. eks. dietyleter, dioksan eller tetrahydro-furan i betraktning. Reduksjoner med natrium-borhydrid kan også utføres i vann eller en alifatisk alkohol, f. eks. etanol eller propanol. I denne forbindelse skal det også henvises til formaldehyds metylacetal (CH,..O .CH2 .O .CH3). These reduction methods are usually carried out in a solvent. For reduction with an alkali metal and an aliphatic alcohol, the alcohols themselves or, if necessary, aromatic or aliphatic esters, e.g. diethyl ether, fenetol or anisole as solvent. When using a complex metal hydride as a reducing agent, particularly aliphatic or cyclic ethers, e.g. diethyl ether, dioxane or tetrahydrofuran into account. Reductions with sodium borohydride can also be carried out in water or an aliphatic alcohol, e.g. ethanol or propanol. In this connection, reference should also be made to formaldehyde's methyl acetal (CH,..O .CH2 .O .CH3).
Inneholder de på denne måte hydrerte og eventuelt reduserte forbindelser frem-deles Y, og/eller Y2-grupper i form av forestrede eller foretrede hydroksylgrupper, så kan disse grupper omdannes til de tilsvarende frie hydroksylgrupper ved herfor kjente fremgangsmåter. If the compounds hydrogenated and possibly reduced in this way still contain Y and/or Y2 groups in the form of esterified or etherified hydroxyl groups, these groups can be converted into the corresponding free hydroxyl groups by methods known for this.
Disse grupper Y, og Y2 kan f. eks., når de er estergrupper, spaltes med fortynnede, vandige eller alkoholiske oppløsninger av natrium- eller kaliumhydroksyd eller syrer, f. eks. saltsyre eller svovelsyre. Det må selv-følgelig tas hensyn til at en hydrolyse av den til resten R2 bundne fenoksygruppe ikke samtidig finner sted ved denne spaltning. Spaltningsreaksjonen må derfor foretas med passende forsiktighet. Det er derfor tilrådelig ,ikke å la slike forbindelser V og VI reagere med hverandre, når disse som hydroksylgrupper tilstedeværende rester, Y, og Y2 er forestret eller foretret med alkohol eller syrerester, som vanskelig avspaltes. Det har vist seg at bensylalkohol oppfyller denne betingelse, så man derfor hensikts-messig går ut fra forbindelser V og VI, hvis eventuelle hydroksylgrupper Y1 og Y2 er foretret med bensylalkohol eller forestret med eddiksyre. Det er meget lett å fraskille bensylresten ved katalytisk reduksjon. Dette finner allerede sted ved hydreringen av forbindelsenes V og VI reaksjonspro-dukt. Reaksjonen mellom forbindelsen med formelen VI og forbindelsen med formelen V kan utføres både i form av det frie amin eller i form av et salt. Salter av sterke syrer gir mindre gode resultater enn de frie aminer eller salter av svake syrer. Som salter av svake syrer kan man f. eks. anvende acetater, bensoater, propionater eller karbonater. These groups Y and Y2 can, for example, when they are ester groups, be cleaved with dilute, aqueous or alcoholic solutions of sodium or potassium hydroxide or acids, e.g. hydrochloric or sulfuric acid. It must of course be taken into account that a hydrolysis of the phenoxy group bound to the residue R2 does not simultaneously take place during this cleavage. The cleavage reaction must therefore be carried out with appropriate care. It is therefore advisable not to allow such compounds V and VI to react with each other, when these residues, Y and Y2 present as hydroxyl groups, are esterified or esterified with alcohol or acid residues, which are difficult to split off. It has been shown that benzyl alcohol fulfills this condition, so it is appropriate to proceed from compounds V and VI, if any hydroxyl groups Y1 and Y2 are etherified with benzyl alcohol or esterified with acetic acid. It is very easy to separate the benzyl residue by catalytic reduction. This already takes place during the hydration of the reaction product of compounds V and VI. The reaction between the compound of formula VI and the compound of formula V can be carried out both in the form of the free amine or in the form of a salt. Salts of strong acids give less good results than the free amines or salts of weak acids. As salts of weak acids, one can e.g. use acetates, benzoates, propionates or carbonates.
Også hydreringsreaksjonen kan utføres både med saltene og med de frie aminer, men også i dette tilfelle får man mindre gode utbytter med de sterke syrer. Dette gjelder imidlertid ikke når resultatet av forbindelsenes V og VI koplingsreaksjon er et ketoamin. Disse forbindelser reduseres fortrinsvis i form av salter av sterke syrer, f. eks. saltsyre eller svovelsyre. The hydration reaction can also be carried out both with the salts and with the free amines, but also in this case less good yields are obtained with the strong acids. However, this does not apply when the result of the coupling reaction of compounds V and VI is a ketoamine. These compounds are preferably reduced in the form of salts of strong acids, e.g. hydrochloric or sulfuric acid.
Det skal også nevnes at de ved frem-gangsmåten ifølge oppfinnelsen erholdte forbindelser fortrinsvis omdannes til salter av sterke syrer. I denne form er forbindelsene mindre oksyderbare i luft enn de frie aminer eller disses salter med svake syrer. It should also be mentioned that the compounds obtained by the process according to the invention are preferably converted into salts of strong acids. In this form, the compounds are less oxidizable in air than the free amines or their salts with weak acids.
