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.

A synthetic dystroglycan oligosaccharide comprising Formula (I) wherein a repeating disaccharide motif consists of Glucuronic Acid (ClcA) and Xylose (Xyl) having a defined glycosyl connection GlcA-β-(1→3)-Xyl-α-(1→3)-GlcA; wherein either end of the synthetic dystroglycan oligosaccharide is conjugatable with chemical or biological vehicle or support; wherein the non-reducing terminal (II) is conjugatable with any oligosaccharides or groups that can modify a hydroxyl functionality; and wherein the reducing terminal is conjugatable with any tags, oligosaccharides or anything that can modify a hydroxyl functionality.
