Enantioselective preparation of C2-symmetric (−)-(2S,5S)-N-benzyl-trans-2,5-bis(acetoxymethyl)pyrrolidine was carried out by the lipase-catalyzed hydrolysis of racemic diacetate. Organic co-solvent affected the enantioselectivity and 50% DMSO in the phosphate buffer was found to be the optimal solvent system. A possible active site model was also described.
通过脂肪酶催化的外消旋二乙酸酯的水解进行C 2对称(-)-(2S,5S)-N-苄基-反式-2,5-双(乙酰氧基甲基)吡咯烷的对映选择性制备。有机助溶剂会影响对映选择性,磷酸盐缓冲液中的50%DMSO被认为是最佳的溶剂体系。还描述了可能的活动站点模型。
