ABSTRACT Catalytic asymmetric syntheses Involving reduction of ketones and oximes, alkylation of aldehydes, and epoxidation of α,β-unsaturated ketones by the use of polymer-supported catalyst have been described. High enantioselectivities (>90% ee) were obtained in each case. The Insoluble polymeric catalysts can be recycled many times without significant loss of activity and used for a preparation of continuous-flow system.
