Studies Towards the Synthesis of the β‐D‐Xyl‐(1 → 3)‐L‐ara Disaccharide Moiety of OSW‐1 from Ornithogalum saundersiae
摘要:
The OSW-1 disaccharide having 2-O-p-methoxybenzoyl-beta-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 arabinose acceptor 15 was obtained in a three step-one pot sequence from easily available benzyl beta-L-arabinopyranoside.
