A denovoasymmetric approach to the natural product anthraxtetrasaccharide 1 and an analogue 2 with an anomeric hexyl azide group has been developed from acetylfuran. The construction of the tetrasaccharide was achieved by a traditional [3 + 1] glycosylation strategy. An iterative diastereoselective palladium-catalyzedglycosylation, Luche reduction, diastereoselective dihydroxylation, and regioselective
