Abstract

N-Acetyl-D-allosamine and its derivatives were synthesized from tri-O-acetyl-D-glucal based on lipase-catalyzed selective protection of primary alcohols,[3, 3] sigmatropic rearrangement of allylic trichloroacetimidates, and stereoselective ruthenium-catalyzed dihydroxylation. In the course of this study, it was revealed that the Pseudomonas lipase-catalyzed acetylation occurred in a high yield (> 90%) exclusively at the primary alcohols of three Ferrier ...
