Abstract:
A highly efficient kinetic resolution of racemic amino alcohols has been achieved for the first time with a chiral tin catalyst. A chiral organotin compound with 3,4,5-trifluorophenyl groups at the 3,3'-positions of the binaphthyl framework enabled this transformation with excellent yield and high enantioselectivity. The process tolerates aryl- and alkyl-substituted amino alcohols and a variety of other substrates, affording the corresponding products in high enantioselectivity and with s factors up to >500.

Chirality
Chiral objects exhibit a sense of handedness when they interact with another chiral object. For example, our left foot can only fit in the left shoe and not in the right shoe. Achiral objects — objects that have...
