  • Title: Synthesis of the methyl alpha-glycosides of some isomalto-oligosaccharides specifically deoxygenated at position C-4.
    Author: Petráková E, Glaudemans CP.
    Journal: Carbohydr Res; 1995 Dec 27; 279():133-50. PubMed ID: 8593619.
    Abstract:
    Methyl alpha-isomaltoside and methyl alpha-isomaltotrioside specifically deoxygenated at position C-4 of various glucopyranosyl units were synthesized by condensation of either 1,6-di-O-acetyl-2,3-di-O-benzyl-4-deoxy-alpha,beta-D-xylo-hexopyranos e (7) or 1,6-di-O-acetyl-2,3,4-tri-O-benzyl-alpha,beta-D-glucopyranose (10) [mediated by silver perchlorate and tin(IV) chloride] with suitably blocked derivatives of methyl alpha-D-glucopyranoside, its 4-deoxy analog 6, or methyl 4'-deoxy alpha-isomaltoside (13), respectively.
