N, N-Dibenzyl Formamide Dimethyl Acetal and N, N-Dibenzyl Chloromethylene Iminium Chloride: Two Complementary Reagents for the Protection Of Primary Amines as N, N-Dibenzyl Formamidines

Abstract

Two complementary procedures are described for the preparation of N, N-dibenzyl formamidines from primary amines in high yield. The primary amine protective group can be easily introduced on polyhydroxylated molecules and is removable either by hydrolysis or hydrogenolysis.
