title: [Structure of the carbohydrate moiety of carminomycins II and III].
abstract: Saccharides II and III were obtained on catalytic hydrogenolysis of carminomycins II and III. The saccharides contained daunosamine and a nitrogen-free fragment of unknown structure. Crotonic aldehyde in the form of 2,4-dinitrophenylhydrazone and 1,2-propylenglycol in the form of 3,5-dinitrobenzoate were isolated on acid hydrolysis of the saccharides. The study on the chemical and spectral properties (PMR-spectra) of the saccharides, their N,O-acetates and hydrolysis products suggested the structure of th carbohydrate moiety of carminomycins II and III as a disaccharide of daunosamine and acyclic semiacetal of 2,4-desoxytetrose.
