  Synthesis of β-d-glucose oligosaccharides from Phytophthora parasitica

  摘要：

  The glucohexaose, beta-D-Glcp-(1 --> 3)-[beta-D-Glcp-(1 --> 3)-beta-D-Glcp-(1 --> 3)-(3-D-Glcp-(1 --> 6)]-(3-D-Glcp-(1 --> 3)-o-Glcp, was synthesized as its allyl glycoside via 3+3 strategy. The trisaccharide donor, 2,3,4,6-tetra-O-benzoyl-alpha-D-glucopyranosyl-(1 --> 3)-2,4,6-tri-O-acetyl-(3-D-glucopyranosyl-(1 --> 3)-2,4,6-tri-O-acetyl-alpha-D-glucopyranosyl trichloroacetimidate (11), was obtained by 3-selective coupling of isopropyl 4,6-O-benzylidene-1-thio-(3-D-glucopyranoside (2) with 2,3,4,6-tetra-O-benzoyl-(3-D-glucopyranosyl-(1 3)-2-O-acetyl-4,6-O-benzylidene-alpha-D-glucopyranosyl trichloroacetimidate (6), followed by hydrolysis, acetylation, dethiolation, and trichloroacetimidation. Meanwhile, the trisaccharide acceptor, allyl 2,3,4,6-tetra-O-benzoyl-(3-D-glucopyranosyl-(1 --> 3)-2-O-acetyl(3-D-glucopyranosyl-(1 3)-4,6-di-O-acetyl-2-O-benzoyl-alpha-D-glucopyranoside (14), was prepared by coupling of allyl 4,6-di-Oacetyl-2-O-benzoyl-alpha-D-glucopyranoside (12) with 6, followed by debenzylidenation. Condensation of 14 with 11, followed by deacylation, gave the target hexaoside. A (3-(1 ->3)-linked tetrasaccharide 29 was also synthesized with methyl 2-O-benzoyl-4,6-0benzylidene-(3-D-glucopyranosyl-(1-> 3)-2,4,6-tri-O-acetyl-(3-D-glucopyranoside (25) as the acceptor and acylated (3-(1 3)-linked disaccharide 21 as the donor. 2003 Elsevier Ltd.
