A process for the preparation of optically active 3-hydroxypyrrolidine or N-substituted 3-hydroxypyrrolidines, wherein an oxygen atom is inserted stereoselectively into the corresponding pyrrolidines, respectively, by use of a bacterium having hydroxylation activity, or a prokaryotic host-organism having the gene(s) necessary for the hydroxylation, or an enzyme having hydroxylation activity derived therefrom. The bacterium may be selected from strains having alkane hydroxylases, strains degrading alkanes or mono-alicyclic compounds, or strains from the genera Pseudomonas, Mycobacterium, Corynebacterium, Nocardia, Sphingomonas, Cordona, Rhodococcus, Bacillus, Streptomyces, Sebekia and Methylococcus.
一种制备光学活性3-羟基吡咯烷或N-取代的3-羟基吡咯烷的方法,其中通过使用具有羟化活性的细菌或具有羟化所需基因的原核生物宿主或源自其的羟化酶,分别将氧原子立体选择性地插入相应的吡咯烷中。细菌可以从具有烷烃羟化酶、降解烷烃或单环烃化合物的菌株中选择,或从假单胞菌属、分枝杆菌属、诺卡氏菌属、Sphingomonas属、Cordona属、红球菌属、链霉菌属、Sebekia属和Methylococcus属中选择。
