Overriding Felkin Control: A General Method for Highly Diastereoselective Chelation-Controlled Additions to α-Silyloxy Aldehydes

According to the Felkin-Anh and Cram-chelation models, nucleophilic additions to α-silyloxy aldehydes procees through a non-chelation pathway due to the steric and electronic properties of the silyl group, giving rise to Felkin addition products. Herein we describe a general method to promote chelat...
