Although glycosylamines constitute an important group of carbohydrates from the standpoint of biology and medicine, methods for their synthesis typically lack substrate generality and/or result in variable stereoselectivity, especially in complex contexts. In this communication, we report an operationally simple

Ring contraction of the neutral oleandrose sugar in the 14-membered-ring macrolide antibiotic oleandomycin (2) has been accomplished using [(methoxycarbonyl)sulfamoyl]triethylammonium hydroxide inner salt (1). The product of this interesting rearrangement, after methanolic hydrolysis of the 2'-acetate, is the 11-acetyl-3-O-(3"-methoxy-4"-vinylfuranosyl)oleandomycin (12). The
