Abstract

The addition of Grignard reagents to cyclic sulfamidate imines has been developed as a facile method for the synthesis of N-substituted quaternary sulfamidates. By way of ring opening with an appropriate nucleophile, versatile synthons for 1,2-amino alcohols, 1,2-diamines, and β-amino acids are produced.
