Dynamic transformation: A racemization catalyst and the enzyme Candida antarctica lipase B (CALB) were combined in a one‐pot dynamic kinetic resolution (DKR) of primary amines, which were transformed to their corresponding amides in up to 95 % yield and >99 % ee. This chemoenzymatic DKR was also applied to the synthesis of norsertraline (see scheme).
动态转化:将消旋化催化剂和南极假丝酵母脂肪酶B(CALB)结合在一起,形成伯胺的一锅动力学动力学拆分(DKR),并以高达95%的收率和> 99%的转化率转化为相应的酰胺。ee。该化学酶DKR也被用于去甲茶碱的合成(参见方案)。
