  An Efficient Synthesis of Sulfo Lewis X Analog Containing 1-Deoxynojirimycin

  摘要：

  Sulfo Lewis(x) analog containing 1-deoxynojirimycin (13) has been efficiently synthesized. Glycosidation of ethyl 2,3,4-tri-0-benzyl-1-thio-beta-D-fucopyranoside (5) with O-(2,6-di-O-benzoyl-3,4-isopropylidene-beta-D-galactopyranosyl)-(1-->4)-2, 6-di-O-benzoyl-N-benzyloxycarbonyl-1,5-dideoxy-1,5-imino-D-glucitol (4), prepared from O-beta-D-galactopyranosyl-(1-->4)-1,5-dideoxy-1, 5-imino-D-glucitol (1) via 3 steps, and subsequent acid hydrolysis of the isopropylidene group gave the desired trisaccharide diol derivative (7) in good yield. Compound 7 was easily converted into 3'-O-sulfo Lewis(x) analog (13) via 6 steps in high yield.
