Studies towards the synthesis of the β-D-Xyl-(1→ 3)-L-ara disaccharide moiety of OSW-1 from Ornithogalum saundersiae

The OSW-1 disaccharide having 2-O-p-methoxybenzoyl-β-D-xylopyranosyl- (1 → 3)-L-arabinopyranoside structure was obtained as the benzylated 4-O-acetyl derivative 19. Also, the 4,2′-di-O-acetate 18 was synthesized by a short synthetic approach. The arabinos
