Author is Vasamsetty, Laxmaiah; Kong, Xiangwen; Meng, Miao; Yang, Shuang; Xu, Weici; Reddy, Pogula Sreekanth; Fang, Xinqiang.

Racemic mixtures of four stereoisomers are easily formed via many fundamental organic transformations, but the direct utilities of these mixtures were less studied and remain large challenges to date. The authors introduce a new method, i.e., divergent dynamic kinetic resolution, to achieve the separation of racemic mixtures of four stereoisomers. The hypothesis was proved by using a N-heterocyclic carbene-catalyzed benzoin reaction, which afforded two separable diastereomeric products bearing three consecutive stereocenters with good to excellent enantioselectivities. The authors believe that this resolution protocol will find applications in more transformations.
