Diastereomers made to order: In an unprecedented ligand‐controlled process a racemic mixture of four stereoisomers can be converted with high selectivity into each one of the diastereomers of the product, at will (see scheme). The mechanism of this deracemization of epimers, that is, a de‐epimerization, was also studied.
定制的非对映异构体:在前所未有的配体控制过程中,可以将四种立体异构体的外消旋混合物以高选择性任意转化为产物的每种非对映异构体(见方案)。还研究了差向异构体的这种去外消旋化,即去差向异构化的机制。
