The reaction of ammonia with some acetylated and benzoylated monosaccharides. III. derivatives of d-galactose

1. d-Galactose diacetamide has been obtained in the following yields by treatment, with methanolic ammonia, of: the α- and β-forms of pentaacetyl-d-galaotopyranose (24-26%); the α- and β-forms of pentaacetyl-d-galactofuranose (42-44%); pentaacetyl-aldehydro-d-galactose (49%); and hexaacetyl-d-gala-l...
