An electrochemical synthesis of methyl α-isomaltoside

Article abstract of DOI:10.1016/0008-6215(94)00218-5

A novel approach has been developed for the synthesis of methyl α-isomaltoside (10), comprising, as the first step, electrochemical conversion of the hydroxyl groups of methyl α-D-glucopyranoside into the corresponding anions.The anions subsequently react with tetra-O-acetyl-α-D-glucopyranosyl bromide to give methyl 2',3',4',6'-tetra-O-acetyl-α-isomaltoside (8) as the main product.O-deacetylation of which affords 10.The glycosidation proceeds under complete stereochemical control.Keywords: Isomaltoside, methyl α-; Disaccharides; Electrochemical synthesis; Structure
