The reaction of ammonia with acylated disaccharides. Part IX. Acetyl derivatives of melibiose

The reaction of methanolic or aqueous ammonia with octa-O-acetyl-β-melibiose gives N-acetyl-6-O-α-D-galactopyranosyl-β-D-glucofuranosylamine (I), and 1,1-bis(acetamido)-1-deoxy-6-O-α-D-galactopyranosyl-D-glucitol (IV). The structure of the furanoid compound was demonstrated by oxidation with perioda...
