Abstract

A simple and straightforward method for the stereocontrolled synthesis of β-linked N-glycosides uses alkyl and aryl azides as the nitrogen source. The N-glycosides are formed in high yields and with high β selectivities (typically >70 % yield, >15:1 β:α selectivity). This approach is also amenable to the synthesis of N-glycosylated amino acids and peptides (see example, Fmoc=9-fluorenylmethoxycarbonyl).
