• Direct and stereoselective synthesis of β-d-mannosides using 4,6-O-benzylidene-protected mannosyl diethyl phosphite as a donor

  A direct and practical method for the construction of β-mannosidic linkages is described. While β-selectivities in the TMSOTf-promoted glycosidation of 2,3,4,6-tetra-O-benzyl-d-mannosyl diethyl phosphite are found to be highly dependent on the reactivity of acceptor alcohols, 2,3-di-O-benzyl-4,6-O-benzylidene-d-mannosyl diethyl phosphite reacts with a wide range of acceptor alcohols in the presence

• A stereocontrolled construction of 2-azido-2-deoxy-1,2-trans-β-glycosidic linkages utilizing 2-azido-2-deoxyglycopyranosyl diphenyl phosphates

  日期：2003.8

  A high-yielding and stereocontrolled construction of 2-azido-2-deoxy-1,2-trans-beta-glycosidic linkages has been achieved by exploiting TMSOTf-promoted 1,2-trans-glycosidation of 2-azido-2-deoxyglycopyranosyl diphenyl phosphates with various glycoside alcohols in propionitrile at -78degreesC. The present method exhibits the highest levels of 1,2-trans-beta-selectivity reported to date for this type of glycosidation. (C) 2003 Elsevier Ltd. All rights reserved.
• A highly stereoselective construction of 1,2-trans-β-glycosidic linkages capitalizing on 2-azido-2-deoxy-d-glycosyl diphenyl phosphates as glycosyl donors

  The scope of TMSOTf-promoted glycosidation of 2-azido-2-deoxyglycopyranosyl diphenyl phosphates is investigated. The 3,4,6-tri-O-benzyl-protected glucosyl and galactosyl donors and the 4,6-O-benzylidene-protected galactosyl donor each react with a range of acceptor alcohols in the presence of a stoichiometric amount of TMSOTf in propionitrile at -78 degreesC to afford 1,2-trans-beta-linked disaccharides in high yields with alpha:beta ratios ranging from 9:91 to 1: > 99, regardless of the anomeric composition of the donor used. The use of propionitrile as a solvent at -78 degreesC has proven to be among the best choice for the highest levels of beta-selectivity reported to date for this type of glycosidation. A plausible reaction mechanism, which features a large equilibrium preference for alpha-glycosyl-nitrilium ions over beta-nitrilium ions, is proposed based on byproducts formed through their intermediacy and accounts for the observed excellent beta-selectivities.
