| 英文摘要 | An octasaccharide, beta-D-Galp-(1 --> 6)-[alpha-L-Araf-(1--> 2)-beta-D-Galp-(1--> 6)-beta-D-Galp-(1--> 6)-[alpha-L-Araf-(1--> 5)-alpha-L-Araf(1 --> 2]-beta-D-Galp-(1--> 6)-beta-D-Galp-1--> OMP was synthesized. 4-Methoxyphenyl 2,3,4-tri-O-benzoyl-beta-D-galactopyranoside (5), 2,6-di-O-acetyl-3,4-di-O-benzoyl-alpha-D-galactopyranosyl trichloroacetimidate (9), and 4-methoxyphenyl 2-O-acetyl-3,4-di-O-benzoyl-beta- D-galactopyranoside (11), 2,3,4,6-tetra-O-benzoyl-alpha-D-galactopyranosyl trichloroacetimidate (12), and 2,3,5-tri-O-benzoyl-alpha-L-arabinofuranosyl trichloroacetimidate (17) were used as the synthons. A concise route was used to gain the tetrasaccharide donor 19 by the use of 11, 12, 5, and 17. Meanwhile, treatment of 5 with 9 yielded beta-(1--> 6)-linked disaccharide 20, and subsequent selective 6-O-deacetylation produced the disaccharide acceptor 21. Reaction of 21 with 19 gave 22, and subsequent selective 2-O-deacetylation afforded the hexasaccharide acceptor 23. Condensation of 23 with alpha-L-(1--> 5)-linked arabinofuranose disaccharide 24, followed by deprotection, yielded the target octasaccharide. (C) 2003 Elsevier Ltd. All rights reserved. |
