A process for the preparation of a pharmaceutically active compound in a stereospecific form of the formula
or a pharmaceutically acceptable salt thereof, like an acid addition salt, and/or a compound in a stereospecific form of the formula
wherein R, is an optionally substituted aryl group including a phenyl or naphthyl group optionally included in a heterocyclic ring system, which is optionally substituted, or is a heteroaromatic 5 or 6 membered ring containing in addition to carbon atoms, one or more atoms selected from nitrogen, sulphur and oxygen, this ring being optionally substituted, and wherein R2 is an alkyl group of 2 to 6 carbon atoms, this alkyl group being optionally substituted, which comprises subjecting a compound of the formula
to the action of a micro-organism having the ability for stereoselective epoxidation of compound (III) into compound (II), having at feast 80% by weight the S configuration, at least partly separating compound (II) andlor reacting compound (II) with a C2-C6 alkylamine group optionally substituted and at least partly separating compound (I) and/or converting compound (I) into the pharmaceutically acceptable salt thereof.
一种制备式中立体特异形式的药用活性化合物的工艺
或其药学上可接受的盐,如酸加成盐,和/或式 3 的立体特异性形式的化合物的工艺
其中 R,是任选被取代的芳基,包括任选包含在杂环系统中的苯基或萘基,该杂环系统是任选被取代的,或者是除碳原子外还含有一个或多个选自氮、硫和氧的原子的杂芳香族 5 或 6 成员环,该环是任选被取代的,其中 R2 是 2 至 6 个碳原子的烷基,该烷基是任选被取代的。
使化合物(III)在具有立体选择性环氧化能力的微生物作用下转化为化合物(II),其 S 构型的重量比不低于 80%,至少部分分离化合物(II),并使化合物(II)与任选被取代的 C2-C6 烷基胺基团反应,至少部分分离化合物(I)和/或将化合物(I)转化为其药学上可接受的盐。
