Simple and efficient: The combination of an enzymatic, enantioinverting reaction with simple follow‐up processes allows the transformation of readily available racemic compounds into versatile chiral α‐substituted amides (see picture; Ms=methanesulfonyl). These important building blocks are prepared in high overall yield and enantiomeric excess; the elimination of intermediate purification steps results
简单高效:酶促对映体转化反应与简单的后续流程相结合,可将现成的外消旋化合物转化为通用的手性α-取代酰胺(见图片; Ms =甲磺酰基)。这些重要组成部分的制备具有很高的总收率和对映体过量;消除中间纯化步骤可节省时间和成本。
