A new route to the disaccharide moiety (2-O-(3-O-carbamoyl-α-D-mannopyranosyl)-L-gulopyranose) of the antitumor agent bleomycin was developed. Both the L-gulose synthon 21 and the 3-O-carbamoyl-D-mannose segment 30 were prepared from D-mannose in a regioselective manner by applying stannylene acetal methodology. Glycosylation of 21 with 30 proceeded smoothly, and further conversion to disaccharide derivatives (33 and 34) was successfully accomplished.
