å omdanne et salt til en fri forbindelse; og/eller, hvis ønskelig, to convert a salt into a free compound; and/or, if desired,
å separere en blanding av isomerer til de enkelte isomerer. to separate a mixture of isomers into the individual isomers.
Omsetningen av en forbindelse med formel (II) med et amin med formel (III) er en reduktiv aminering som kan gjennomføres ved behandling med et egnet reduksjonsmiddel, for eksempel et alkalisk borhydrid som NaBE4 eller NaB^CN. Reaksjonen kan gjennomføres i et egnet organisk oppløsningsmiddel, for eksempel en alifatisk alkohol, fortrinnsvis en laverealkanol som metanol eller etanol, ved en temperatur innen området ca. 0 til 20° C, i nærvær av et overskudd av et amin med formel (II), slik det for eksempel beskrives I "J. Med. Chem.", 1980, 23, 750. The reaction of a compound of formula (II) with an amine of formula (III) is a reductive amination which can be carried out by treatment with a suitable reducing agent, for example an alkaline borohydride such as NaBE 4 or NaB^CN. The reaction can be carried out in a suitable organic solvent, for example an aliphatic alcohol, preferably a lower alkanol such as methanol or ethanol, at a temperature within the range of approx. 0 to 20° C, in the presence of an excess of an amine of formula (II), as described for example in "J. Med. Chem.", 1980, 23, 750.
Reduksjonen av en forbindelse med formel (IV) kan generelt gjennomføres ved de metoder som vanligvis benyttes for reduksjoner av amider, for eksempel ved behandling med L1A1H4, ÅIE3 eller BH3 i et Inert, vannfritt oppløsnings-middel, fortrinnsvis en alifatisk eter, for eksempel dietyleter eller tetrahydrofuran, eller en blanding av disse oppløsningsmidler ved temperaturer som varierer fra ca. 0 til 20°C, som for eksempel beskrevet i "J. Med. Chem.", 1981, 24, 982 eller ved behandling med et alkalisk borhydrid, for eksempel NaBH4, i nærvær av alkalimetaller som for eksempel beskrevet i "Tetr. Lett.", 1969, 4555. The reduction of a compound of formula (IV) can generally be carried out by the methods usually used for the reduction of amides, for example by treatment with L1A1H4, ÅIE3 or BH3 in an inert, anhydrous solvent, preferably an aliphatic ether, for example diethyl ether or tetrahydrofuran, or a mixture of these solvents at temperatures varying from approx. 0 to 20°C, as for example described in "J. Med. Chem.", 1981, 24, 982 or by treatment with an alkaline borohydride, for example NaBH4, in the presence of alkali metals as for example described in "Tetr. Lett .”, 1969, 4555.
Når Z i en forbindelse med formel (V) er en avspaltbar gruppe, er den for eksempel klor eller en mesyloksy-, tosyloksy- eller trifluoracetatgruppe. When Z in a compound of formula (V) is a leaving group, it is for example chlorine or a mesyloxy, tosyloxy or trifluoroacetate group.
Omsetningen av en forbindelse med formel (V) med et amin med formel (VI) er en vanlig nukleofil substitusjon som er godt dekket i litteraturen. Reaksjonen gjennomføres fortrinnsvis I et egnet organisk oppløsningsmiddel som dimetylformamid, dimetylsulfoksyd eller C1_4~alkanol, fortrinnsvis metanol eller etanol, dioksan, tetrahydrofuran eller en blanding derav, ved en temperatur fortrinnsvis mellom 20 og 100°C. The reaction of a compound of formula (V) with an amine of formula (VI) is a common nucleophilic substitution which is well covered in the literature. The reaction is preferably carried out in a suitable organic solvent such as dimethylformamide, dimethylsulfoxide or C1-4~alkanol, preferably methanol or ethanol, dioxane, tetrahydrofuran or a mixture thereof, at a temperature preferably between 20 and 100°C.
En forbindelse med formel (I) kan som angitt ovenfor omdannes til en annen forbindelse med formel (I) på kjent måte. For eksempel kan en fri hydroksygruppe foretres ved omsetning med et egnet alkylhalogenid i nærvær av en base som NaOH, KOH, Na£C03, K2CO3, NaE, NaNH2, natriummetoksyd eller natrium-etoksyd i et oppløsningsmiddel hensiktsmessig valgt blant gruppen som omfatter metanol, etanol, dioksan, aceton, dimetylformamid, heksametylfosfortriamid, tetrahydrofuran, vann og deres blandinger, ved en temperatur som fortrinnsvis ligger innen området 0 til 150°C. As indicated above, a compound of formula (I) can be converted into another compound of formula (I) in a known manner. For example, a free hydroxy group may be esterified by reaction with a suitable alkyl halide in the presence of a base such as NaOH, KOH, Na£CO 3 , K 2 CO 3 , NaE, NaNH 2 , sodium methoxide or sodium ethoxide in a solvent suitably selected from the group comprising methanol, ethanol , dioxane, acetone, dimethylformamide, hexamethylphosphoric triamide, tetrahydrofuran, water and their mixtures, at a temperature which is preferably within the range of 0 to 150°C.
Alkyleringen av en fri aminogruppe kan gjennomføres i henhold til kjent metoder. For eksempel kan en forbindelse med formel (I) der en av R^ og R2 som angitt ovenfor er hydrogen, alkyleres for å oppnå det tilsvarende alkyl-, alkenyl-, alkynyl- eller aralkylderivat. Alkyleringsreaksjonen kan for eksempel gjennomføres ved behandling med det egnede alkyl-, alkenyl-, alkynyl- eller aralkylhalogenid eller med en reaktiv ester, for eksempel tosylat eller mesylat, av den egnede alkohol. Alkyleringen kan gjennomføres enten i fravær av oppløsningsmidler eller i et oppløsningsmiddel, for eksempel en alifatisk alkohol som etyl- eller metylalkohol, en glykol som etylenisk eller propylenisk glykol, benzen eller dimetylformamid, eller en blanding av disse oppløs-ningsmidler i nærvær av en syreakseptor som trietylamin, et alkalikarbonat eller —bikarbonat eller et overskudd av aminet, ved en temperatur innen området romtemperatur til oppløsningsmidlets tilbakeløpstemperatur i henhold til de prosedyrer som for eksempel er beskrevet i "J. Org. Chem.", 1938, 2, 139; "Org. Synt. Coll.", vol. II, 1943, 183; "J. Amer. Chem. Soc", 1932, 54, 4457. The alkylation of a free amino group can be carried out according to known methods. For example, a compound of formula (I) in which one of R 1 and R 2 as indicated above is hydrogen, can be alkylated to obtain the corresponding alkyl, alkenyl, alkynyl or aralkyl derivative. The alkylation reaction can, for example, be carried out by treatment with the suitable alkyl, alkenyl, alkynyl or aralkyl halide or with a reactive ester, for example tosylate or mesylate, of the suitable alcohol. The alkylation can be carried out either in the absence of solvents or in a solvent, for example an aliphatic alcohol such as ethyl or methyl alcohol, a glycol such as ethylene or propylene glycol, benzene or dimethylformamide, or a mixture of these solvents in the presence of an acid acceptor which triethylamine, an alkali carbonate or bicarbonate or an excess of the amine, at a temperature within the range of room temperature to the reflux temperature of the solvent according to the procedures described, for example, in "J. Org. Chem.", 1938, 2, 139; "Org. Synt. Coll.", vol. II, 1943, 183; "J. Amer. Chem. Soc", 1932, 54, 4457.
Monoalkyleringen kan alternativt gjennomføres ved de metoder som for eksempel er beskrevet i "J. Org. Chem.", 1975, 40, 3453; "J. Chem. Soc.", 1969, 2223; "J. Med. Chem.", 1974, 17, 654. The monoalkylation can alternatively be carried out by the methods described, for example, in "J. Org. Chem.", 1975, 40, 3453; "J. Chem. Soc.", 1969, 2223; "J. Med. Chem.", 1974, 17, 654.
Videre er den eventuelle saltdannelse av en forbindelse med formel (I) velkjent på samme måte som omdanningen av et salt til den frie forbindelse og separeringen av en blanding av isomerer til de enkelte isomerer, kan gjennomføres ved konvensjonelle metoder. Furthermore, the possible salt formation of a compound of formula (I) is well known in the same way that the conversion of a salt to the free compound and the separation of a mixture of isomers into the individual isomers can be carried out by conventional methods.
Separeringen av en blanding av geometriske isomerer kan for eksempel gjennomføres ved fraksjonert krystallisering eller ved separering ved kolonnekromatografi. The separation of a mixture of geometric isomers can be carried out, for example, by fractional crystallization or by separation by column chromatography.
Separeringen av isomerene, for eksempel Z- og E-isomerene, til de enkelte isomerer, kan gjennomføres på sluttproduktene med formel (I), eller på mellomproduktene derav. The separation of the isomers, for example the Z and E isomers, into the individual isomers can be carried out on the final products of formula (I), or on the intermediate products thereof.
I de prosesser som er beskrevet her kan hvis nødvendig, reaktive funksjonelle grupper beskyttes med egnede beskyt-telsesmidler som kan fjernes efter reaksjonen ved I og for seg kjente metoder som finnes i litteraturen. In the processes described here, if necessary, reactive functional groups can be protected with suitable protective agents which can be removed after the reaction by per se known methods found in the literature.
Forbindelsene med formel (II) kan oppnås ved å redusere en forbindelse med formel (VII): The compounds of formula (II) can be obtained by reducing a compound of formula (VII):
der there
R 3 og R4 er som angitt ovenfor og W for eksempel er halogen, spesielt klor, eller laverealkoksy, ved hjelp av et egnet selektivt reduksjonsmiddel. R 3 and R 4 are as indicated above and W is, for example, halogen, especially chlorine, or lower alkoxy, by means of a suitable selective reducing agent.
Spesielt kan når W er klor, tritert-butoksy-litiumaluminiumhydrid benyttes, analogt kan når W er laverealkoksy, dlisobutylaluminiumhydrid benyttes, som beskrevet for eksempel i "Eur. J. Med. Chem.", 1984, 19, 235 eller i "J. Org. Chem.", 1976, 41, 3512. In particular, when W is chlorine, tritert-butoxy-lithium aluminum hydride can be used, analogously when W is lower alkoxy, diisobutylaluminum hydride can be used, as described for example in "Eur. J. Med. Chem.", 1984, 19, 235 or in "J. Org. Chem.", 1976, 41, 3512.
Reaksjonen kan gjennomføres I organiske oppløsningsmidler, for eksempel tetrahydrofuran, diglym eller toluen, ved temperaturer i området ca. -60 til +20°C. Alternativt kan forbindelsene med formel (II) oppnås ved omsetning av en forbindelse med formel (VIII): med et hydroksyderivat med formel The reaction can be carried out in organic solvents, for example tetrahydrofuran, diglyme or toluene, at temperatures in the range of approx. -60 to +20°C. Alternatively, the compounds of formula (II) can be obtained by reacting a compound of formula (VIII): with a hydroxy derivative of formula
Reaksjonen kan gjennomføres i en egnet C^^-alkanol som metanol eller etanol, i nærvær av et basisk middel som pyridin, for eksempel som beskrevet i J. Chem. Soc", Perkin I, 1981, 1103 eller i aprotiske dipolare oppløsningsmidler som DMF eller DMSO. The reaction can be carried out in a suitable C 12 -alkanol such as methanol or ethanol, in the presence of a basic agent such as pyridine, for example as described in J. Chem. Soc", Perkin I, 1981, 1103 or in aprotic dipolar solvents such as DMF or DMSO.
Forbindelsene med formel (IV) kan oppnås for eksempel ved omsetning av en forbindelse med formel (VII) der W er halogen, for eksempel klor, med en vandig oppløsning av et amin med formel HNR]R2, der R^ og R2 er som angitt ovenfor, ved romtemperatur. The compounds of formula (IV) can be obtained, for example, by reacting a compound of formula (VII) where W is halogen, for example chlorine, with an aqueous solution of an amine of formula HNR]R 2 , where R 1 and R 2 are as indicated above, at room temperature.
Den samme reaksjon kan gjennomføres ved å benytte en forbindelse med formel (VII) der W er laverealkoksy, for eksempel C1_4~alkoksy og fortrinnsvis metoksy eller etoksy, og en DMF-, DMA- eller dioksanoppløsning av aminet HNR1R2, ved en temperatur innen området ca. 80 til 100<*>C. ;Forbindelsene med formel (V) kan oppnås ved å redusere en forbindelse enten med formel (II) eller med formel (VII) til den tilsvarende alkohol og derefter å omdanne den alkoholiske gruppe i en Z-avspaltbar gruppe som angitt ovenfor. Reduksjonen av en forbindelse med formel (II) oppnås fortrinnsvis ved hjelp av et alkaliborhydrid, for eksempel NaBH4, I en laverealkanol. Tilsvarende reduksjon av en forbindelse med formel (VII) gjennomføres fortrinnsvis med LiAlH4 i dietyleter eller tetrahydrofuran ved temperaturer innen området -10 til 50<*>C. Den efterfølgende omdanning av den alkoholiske gruppe til en Z-avspaltbar gruppe kan oppnås ved omsetning for eksempel av mesyl- eller tosylklorid eller av et derivat av trifluoreddiksyre, for eksempel trifluoreddiksyreanhydrid, eller det alkaliske salt av alkoholen, i et aprotisk dipolart oppløsningsmiddel som DMF eller DMSO, for derved å oppnå en forbindelse med formel (I) hvori Z er mesyloksy eller tosyloksy eller henholdsvis trifluoracetat. Ved omsetning av alkoholen med trifenylfosfin og CCI4 som beskrevet i "J. Org. Chem.", 1972, 37, 1466 kan det analogt oppnås en forbindelse med formel (V) der Z er klor. The same reaction can be carried out by using a compound of formula (VII) where W is lower alkoxy, for example C1_4~ alkoxy and preferably methoxy or ethoxy, and a DMF, DMA or dioxane solution of the amine HNR1R2, at a temperature within the range of approx. . 80 to 100<*>C. The compounds of formula (V) can be obtained by reducing a compound of either formula (II) or of formula (VII) to the corresponding alcohol and then converting the alcoholic group into a Z-cleavable group as indicated above. The reduction of a compound of formula (II) is preferably achieved by means of an alkali borohydride, for example NaBH 4 , in a lower alkanol. Corresponding reduction of a compound of formula (VII) is preferably carried out with LiAlH4 in diethyl ether or tetrahydrofuran at temperatures within the range -10 to 50<*>C. The subsequent transformation of the alcoholic group into a Z-cleavable group can be achieved by reacting, for example, mesyl or tosyl chloride or a derivative of trifluoroacetic acid, for example trifluoroacetic anhydride, or the alkaline salt of the alcohol, in an aprotic dipolar solvent such as DMF or DMSO, thereby obtaining a compound of formula (I) in which Z is mesyloxy or tosyloxy or trifluoroacetate respectively. By reacting the alcohol with triphenylphosphine and CCl 4 as described in "J. Org. Chem.", 1972, 37, 1466, a compound of formula (V) where Z is chlorine can be obtained analogously.
Forbindelsene med formel (VII)- der W er laverealkoksy, for eksempel C1_4~alkoksy, kan oppnås ved å gå ut fra en forbindelse med formel (IX): der R3 og R4 er som angitt ovenfor, ved omsetning med en Wittig-reagens, for eksempel et fosforylid med formel (X) The compounds of formula (VII)- where W is lower alkoxy, for example C1_4~ alkoxy, can be obtained starting from a compound of formula (IX): where R3 and R4 are as indicated above, by reaction with a Wittig reagent, for example a phosphorylide of formula (X)
der Q er C1_4~alkyl eller aryl, for eksempel fenyl, og V er laverealkoksy, for eksempel i henhold til den metode som er beskrevet i FR-PS 2 480 283. where Q is C1_4~alkyl or aryl, for example phenyl, and V is lower alkoxy, for example according to the method described in FR-PS 2 480 283.
En forbindelse med formel (VII) der W er halogen, for eksempel klor, kan oppnås for eksempel ved A compound of formula (VII) where W is halogen, for example chlorine, can be obtained for example by
1) hydrolysering av den tilsvarende karboksyliske ester med formel (VII) til den frie karboksyl syre, for eksempel ved basisk hydrolyse i et alkoholisk eller vandig-alkoholisk medium og derefter 1) hydrolysis of the corresponding carboxylic ester of formula (VII) to the free carboxylic acid, for example by basic hydrolysis in an alcoholic or aqueous-alcoholic medium and then
2) oppvarming av natriumsaltet av karboksylsyren og diklor-metyl-metyleter ved temperaturer fra ca. 50°C til 100°C, som beskrevet for eksempel i "Ber.", 1969, 92, 83. 2) heating the sodium salt of the carboxylic acid and dichloro-methyl-methyl ether at temperatures from approx. 50°C to 100°C, as described for example in "Ber.", 1969, 92, 83.
