Abstract

Phase-transfer alkylation of the benzophenone Schiff base of glycine methyl or ethyl ester () was found to be catalyzed by 3, 4, 5-F3-C6H2-NAS-Br [] with high efficiency and excellent enantioselectivity. This procedure allows facile derivatization of the resulting alkylation products to other synthetically useful chiral building blocks.
