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-manno-heptononitrile (34%). 2. An explanation is given correlating the difference in yields with the structure and the possible reaction course for each type of compound. 3. Treatment of pentabenzoyl-α-d-galactose with methanolic ammonia produces d-galactose dibenzamide. © 1952, American Chemical Society. All rights reserved.
