Abstract

New oxamides, derivatives of D-glucosamine and aliphatic or aromatic amines were prepared by acylation of methyl 3,4,6-tri-O-acetyl-2-acetamido-2-deoxy-α- or -β-D-glucopyranoside (1c or 1d) with oxalyl chloride, followed by reaction with amine. The reaction was assumed to proceed by the intermediate of N-carbomethoxy N-(methyl 3,4,6-tri-O-acetyl-2-deoxy-α or β-D-glucopyranosid-2-yl) oxamic acid chloride which reacted with amines, and afforded N-acetyl, N-(methyl 3,4,6-tri-O-acetyl-2-deoxy-α- or -β-D-glucopyranosid-2-yl), N′-alkyl or aryloxamide (5–7), and N-(methyl 3,4,6-tri-O-acetyl-2-deoxy-α- or -β-D-glucopyranosid-2-yl), N′-alkyl or aryloxamide (8–13).
