Biocatalytic reductive amination catalyzed by engineered imine reductase (RedAms) is a new and powerful tool for the synthesis of substituted chiral amines. Herein, we describe a streamlined synthesis of compound 3, a key intermediate to a CDK 2/4/6 inhibitor 1, relying on the enzymatic reductive amination of a hydroxyketone to introduce the chiral secondary amine with high diastereoselectivity.

工程亚胺还原酶(RedAms)催化的生物催化还原胺化是合成取代手性胺的一种新的强大工具。在此,我们描述了化合物 3 的流线型合成,化合物3是 CDK 2/4/6 抑制剂1的关键中间体,依靠羟基酮的酶还原胺化来引入具有高非对映选择性的手性仲胺。还介绍了通过钛催化还原环化改进的羟基酮前体合成和两个 S N Ar 反应过程中的工艺开发3。
