was observed in the presence of Candida antarctica Lipase B, in which a >60% yield of (R)-acetamide [(R)-2] was isolated from the racemic amine. The spontaneous formation of ketone 3, followed by a condensation/hydrolysis sequence with the remaining (S)-amine 1, via enamine 4, provides the necessary racemization pathway.
在南极假丝酵母脂肪酶B存在的情况下,观察到了8-氨基-5,6,7,8-四氢喹啉1的自发动态动力学拆分,其中(R)-乙酰胺[(R)-2]的收率> 60%从外消旋胺中分离出]。酮3的自发形成,然后通过烯胺4与其余(S)-胺1的缩合/水解过程提供了必要的消旋途径。
