  This invention provides a process for the preparation of optically active 4-hydroxy-2-pyrrolidinone or N-substituted 4-hydroxy-2-pyrrolidinones, wherein an oxygen atom is inserted regio- and stereoselectively into the corresponding non-hydroxylated 2-pyrrolidinones, by using, as a biocatalyst, a microorganism having hydroxylation activity, or a host-organism having the gene(s) necessary for the hydroxylation enzymes derived from the said microorganism, or an enzyme having hydroxylation activity derived from the above microorganisms. The microorganism may be selected from the group consisting of microorganisms that degrade alkanes or cyclic hydrocarbons, microorganisms having alkane hydroxylase(s), or microorganisms that are able to oxidize hydrocarbons.

  本发明提供了一种制备光学活性4-羟基-2-吡咯烷酮或N-取代的4-羟基-2-吡咯烷酮的方法，其中将氧原子以区域和立体选择性插入相应的非羟基化2-吡咯烷酮中，使用具有羟化活性的微生物或具有来自所述微生物的羟化酶所必需的基因的宿主生物作为生物催化剂，或者使用来自上述微生物的羟化酶活性的酶。微生物可以从降解烷烃或环烃的微生物、具有烷烃羟化酶的微生物或能够氧化碳氢化合物的微生物中选择。
