Synthesis of two oligosaccharides, the GPI anchor glycans from S. cerevesiae and A. fumigatus
Two oligosaccharides, alpha-D-Manp-(1?2)-alpha-D-Manp-(1?2)- alpha-D-Manp-(1?6)-alpha-D-Manp-(1?4)-alpha-D-GlcpNAc (I) and alpha-D-Manp-(1?3)-alpha-D-Manp-(1?2)-alpha-D-Manp-(1?2) -alpha-D-Manp-(1?6)-alpha-D-Manp-(1?4)-alpha-D-GlcpNAc (II), the glycosylphosphatidylinositol (GPI) anchor glycans from S. cerevesiae and A. fumigatus were synthesized as their methyl glycosides in a regio- and stereoselective manner. The pentasaccharide I was obtained from 6-O-selective glycosylation of methyl 2,3-di-O-benzoyl-alpha-D-mannopyranosyl-(1?4)-2- acetamido-3,6-di-O-benzoyl-2-deoxy-alpha-D-glucopyranoside (8) with 2-O-acetyl-3,4,6-tri-O-benzoyl-alpha-D-mannopyranosyl-(1?2)-3,4, 6-tri-O-benzoyl-alpha-D-mannopyranosyl trichloroacetimidate (9), followed by benzoylation, deacetylation, and mannosylation, and then by deprotection. The hexasaccharide (II) was obtained via condensation of allyl 3,4,6-tri-O-benzoyl- alpha-D-mannopyranosyl-(1?2)-3,4,6-tri-O-benzoyl-alpha-D- mannopyranoside (17) with 2,3,4,6-tetra-O-benzoyl-alpha-D-mannopyranosyl- (1?3)-2,4,6-tri-O-acetyl-alpha-D-mannopyranosyl trichloroacetimidate (16), followed by deallylation, trichloroacetimidation, and coupling with acceptor (8), and finally by deprotection.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 14215-68-0 is helpful to your research., Related Products of 14215-68-0
