[Glycosilated derivatives of substituted hydroxylamine. II. Phase transfer synthesis and investigation of glycosyl transfer reaction of glucosaminides of substituted hydroxylavine].

Abstract

1-(2-Acetamido-3,4,6,-tri-O-acetyl-2-deoxy-beta-D-glucopyranosyloxy)-benzotriazole reacted in boiling dichloromethane, in the presence of Luis acids as a promotors with primary and secondary aliphatic and cycloaliphatic alcohols and diisopropilidene galactose with alkyl-O-1,2-trans-glucosaminides formation. It was shown that the other glucosaminides of substituted hydroxylamine are not participated in this reaction. Structures of glucosaminides were identify by 1H-NMR-spectroscopy and comparison with known compounds.
