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
