Werkwijze voor de bereiding van 2—(E)-fenylmethyleencyclo-heptan-1-on-(E)-oxim-Process for the preparation of 2— (E) -phenylmethylene-cyclo-heptan-1-one- (E) -oxime-
De uitvinding heeft betrekking op een werkwijze voor de bereiding van 2-(E)-fenylmethyleencycloheptan-l-on- (E)-oxim met de formule I van het formuleblad, vrij van andere isomeren. De verbinding met formule I dient als tussenprodukt 5 dat bruikbaar is bij de synthese van derivaten met waardevolle farmaceutische eigenschappen, bijv. bij de synthese van de verbindingen beschreven in het Hongaarse octrooischrift 169.289.The invention relates to a process for the preparation of 2- (E) -phenylmethylene-cycloheptan-1-one- (E) -oxime of the formula I of the formula sheet, free from other isomers. The compound of formula I serves as an intermediate 5 which is useful in the synthesis of derivatives of valuable pharmaceutical properties, e.g. in the synthesis of the compounds described in Hungarian patent 169,289.
Tot dusver werd in de literatuur geen methode beschreven voor de bereiding van de verbinding met formule I.To date, no method has been described in the literature for the preparation of the compound of formula I.
10 - Het is bekend dat ketonen een interactie ver tonen met hydroxylamine dat in situ is verkregen uit een hydroxylaminezout in aanwezigheid van een base. De reactie leidt tot een oxim. De structurele eigenschappen van het uit-gangsketon in aanmerking genomen kunnen twee isomeren worden 15 gevormd in de reactie. In meer eenvoudige gevallen worden deze ,rsynH resp. 11 anti" genoemd, terwijl in het geval van verbindingen met een meer gecompliceerde structuur de aanduidingen "Z" resp. "E" worden gebruikt.10 - Ketones are known to interact with hydroxylamine obtained in situ from a hydroxylamine salt in the presence of a base. The reaction results in an oxime. Considering the structural properties of the starting ketone, two isomers can be formed in the reaction. In simpler cases these, rsynH resp. 11 are called anti ", while in the case of compounds of a more complicated structure, the designations" Z "and" E "are used.
Het is bekend dat de verschillende isomeren 20 verschillende biologische eigenschappen bezitten. Dat is de reden waarom in veel gevallen het noodzakelijk is deze in zuivere vorm te bereiden, hetgeen slechts uit tussenprodukten die vrij van isomeren zijn, kan worden bereikt.The different isomers are known to have different biological properties. That is why in many cases it is necessary to prepare them in pure form, which can only be achieved from isomer-free intermediates.
Het doel van onze onderzoekingen was een werk-25 wijze uit te werken die geschikt is voor de bereiding van het 2-(E)-fenylmethyleencycloheptan-l-on-(E)-oxim, dat vrij is van andere isomeren.The purpose of our studies was to devise a process suitable for the preparation of the 2- (E) -phenylmethylene-cycloheptan-1-one (E) -oxime, which is free from other isomers.
Gevonden werd dat wanneer het 2-(E)-fenyl-methyleencycloheptan-l-on met formule II van het formuleblad 30 tot reactie wordt gebracht met hydroxylamine dat in situ is verkregen uit een hydroxylaminezout in aanwezigheid van een base, in water en/of in een lagere, met water onbeperkt mengbare alifatische alcohol en het alcoholgehalte van het reac-tiemedium tot 40-60 %, bij voorkeur tot 50 %, wordt bijgesteld, 35 vrijwel uitsluitend het gewenste (E,E)-isomeer wordt verkregen.It was found that when the 2- (E) -phenyl-methylene-cycloheptan-1-one of formula II of formula sheet 30 is reacted with hydroxylamine obtained in situ from a hydroxylamine salt in the presence of a base, in water and / or in a lower water-unlimited miscible aliphatic alcohol and the alcohol content of the reaction medium is adjusted to 40-60%, preferably up to 50%, almost exclusively the desired (E, E) isomer is obtained.
Het produkt bevat ten hoogste 5 % aan andere isomeren, die 8301175 - 2 - desgewenst langs bekende wegen verwijderd kunnen worden.The product contains at most 5% of other isomers, which can be removed if desired by known routes.
De uitgangsverbinding met formule II is bekend en kan worden bereid volgens in de literatuur beschreven werkwijzen /bijv.: Gazz. Chim. Ital. '91, 326-48 (1961/7· De 5 hydroxylaminezouten (sulfaat, hydrochloride) zijn commercieel verkri j gbare produkten.The starting compound of formula II is known and can be prepared according to methods described in the literature / e.g. Gazz. Chim. Ital. 91, 326-48 (1961/7) The 5 hydroxylamine salts (sulfate, hydrochloride) are commercially available products.
De reactie van het 2-(E)-fenylmethyleencyclo-heptan-l-on met het hydroxylamine dat in situ wordt verkregen uit een hydroxylaminezout (bij voorkeur sulfaat of hydrochlo-10 ride) wordt in water en/of in een waterige alcohol als medium uitgevoerd. Hiertoe kunnen rechte of vertakte, met water onbeperkt mengbare alifatische alcoholen worden gebruikt, zoals methanol, ethanol, n-propanol, isopropanol, enz. De reactie wordt bij voorkeur uitgevoerd in het mengsel van een alcohol 15 en water, bij voorkeur in een (50-98) : (2-50)-mengsel van deze oplosmiddelen. Wanneer de reactie is afgelopen wordt de alcoholconcentratie bijgesteld tot 40-60, bij voorkeur tot ca. 50 %, door de toevoeging van water (ijs) of alcohol.The reaction of the 2- (E) -phenylmethylene-cyclo-heptan-1-one with the hydroxylamine obtained in situ from a hydroxylamine salt (preferably sulfate or hydrochloride) is in water and / or in an aqueous alcohol as medium executed. To this end, straight or branched water-unlimited miscible aliphatic alcohols such as methanol, ethanol, n-propanol, isopropanol, etc. can be used. The reaction is preferably carried out in the mixture of an alcohol and water, preferably in a (50 -98): (2-50) mixture of these solvents. When the reaction is complete, the alcohol concentration is adjusted to 40-60, preferably to about 50%, by the addition of water (ice) or alcohol.
De reactie wordt uitgevoerd in aanwezigheid van 20 een base. Hiertoe kunnen organische basen (pyridine of pyri-dinebasen, d.w.z. het mengsel van 2-, 3- en 4-picoline en lutidine) of anorganische basen (alkalihydroxiden, -carbonaten of -waterstofcarbonaten) worden gebruikt.The reaction is carried out in the presence of a base. For this purpose, organic bases (pyridine or pyridine bases, i.e. the mixture of 2-, 3- and 4-picoline and lutidine) or inorganic bases (alkali hydroxides, carbonates or hydrogen carbonates) can be used.
De reactietemperatuur beïnvloedt de opbrengst 25 niet in wezenlijke mate en kan binnen een wijd gebied worden gevariëerd. Men werkt in het algemeen tussen 20°C en 90°C,,bij voorkeur tussen 75°C en 85°C.The reaction temperature does not substantially affect the yield 25 and can be varied over a wide range. Generally it is operated between 20 ° C and 90 ° C, preferably between 75 ° C and 85 ° C.
De stereochemische zuiverheid van het zo verkregen 2-(E)-fenylmethyleencycloheptan-l-on-(E)-oxim hangt af 30 van die van het voor de reactie gebruikte 2-(E)-fenylmethyleencycloheptan-l-on. Indien deze laatste verbinding namelijk verontreinigd is met een tamelijk grote hoeveelheid van zijn 2—(Z)-isomeer, neemt het aantal van de mogelijke isomeerver-ontreinigingen tweevoudig toe en kan de onzuiverheid van het 35 zo verkregen produkt de boven gegeven limiet overschrijden.The stereochemical purity of the 2- (E) -phenylmethylene-cycloheptan-1-one (E) -oxime thus obtained depends on that of the 2- (E) -phenylmethylene cycloheptan-1-one used for the reaction. Namely, if the latter compound is contaminated with a fairly large amount of its 2- (Z) -isomer, the number of possible isomer impurities increases two-fold and the impurity of the product thus obtained may exceed the above-given limit.
Indien een bijzonder zuiver produkt noodzakelijk is, kan het in de reactie verkregen ruwe produkt langs op zich bekende wegen worden gezuiverd (bijv. kolomchromatografie, 8301175 Ί» - 3 - destillatie, zonesmelting, kristallisatie uit petroleumether of uit ethanol).If a particularly pure product is necessary, the crude product obtained in the reaction can be purified by means known per se (eg column chromatography, 8301175 - 3 - distillation, zone melting, crystallization from petroleum ether or from ethanol).
De uitvinding wordt toegelicht aan de hand van de volgende niet beperkende voorbeelden.The invention is illustrated by the following non-limiting examples.
