Abstract
Methyl alpha-isomaltoside and methyl alpha-isomaltotrioside specifical ly deoxygenated at position C-3 of various glucopyranosyl units were s ynthesized by condensation of either 1,6-di-O-acetyl-2,4-di-O-benzyl-3 -deoxy-alpha, beta-D-ribo-hexopyranose (7) or etyl-2,3,4-tri-O-benzyl- alpha,beta-D-glucopyranose [mediated by silver perchlorate and tin(IV) chloride] with suitably blocked derivatives of methyl alpha-D-glucopy ranoside, its 3-deoxy analog (6), or methyl 3'-deoxy alpha-isomaltosid e (10), respectively.
