producing enantioenriched monoacetates from prochiral diols and diesters. AK lipase has been found as an excellent biocatalyst for the desymmetriaztion of a series of previously synthesized 3-arylpentane-1,5-diols derivatives. The access to (S)- or (R)-monoacetates in high optical purity (86−99% ee) has been possible by using acetylation or hydrolysis reactions, respectively, where the reaction parameters
已对脱对称酶的酶促过程进行了广泛研究,以寻找从前手性二醇和二酯生产对映体富集的单乙酸酯的最佳方法。AK脂肪酶已被发现是用于脱除一系列先前合成的3-芳基戊烷-1,5-二醇衍生物的极好的生物催化剂。访问(S)-或(R通过使用乙酰化或水解反应,可以分别获得高光学纯度(86-99%ee)的单乙酸酯,其中在生物催化剂的来源和数量,温度,溶剂和反应时间方面对反应参数进行了优化。通过使用这些有趣的手性结构单元来制备新型对映纯羧酸衍生物,已证明了对映纯单酯的合成潜力。
