Abstract
Methyl alpha-isomaltoside and methyl alpha-isomaltotrioside specifical ly deoxygenated at position C-4 of various glucopyranosyl units were s ynthesized by condensation of either di-O-benzyl-4-deoxy-alpha,beta-D- xylo-hexopyranose (7) or etyl-2,3,4-tri-O-benzyl-alpha,beta-D-glucopyr anose (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), respective ly.
