Abstract

A practical procedure has been developed for grafting poly(amino acid) on silica gel as an efficient and recoverable catalyst in the Juliá-Colonna asymmetric epoxidation with high enantioselectivities. Separation and recovery of the catalyst of poly(amino acid) have been remarkably improved by grafting on silica gel without a significant loss of enantioselectivity and activity.
