Efficient and stereoselective synthesis of a disaccharide fragment, 2-deoxy-4-O-(N′-monodemethyl-d-forosaminyl)-2-methylamino-β-d-xylopyranoside, of a novel antibiotic, incednine (1), is described. The key β-stereoselective formation of a 2,3,4,6-tetradeoxy-4-methylamino glycoside bond was achieved by remote participation-assisted glycosylation.
