ABSTRACT:
Anthracycline disaccharides having antitumor activity are prepared by condensing N-trifluoroacetyldaunomycin with a 1-halosugar in the presence of a silver salt such as AgSO.sub.3 CF.sub.3 as catalyst to form a protected di-glycoside which upon mild alkaline hydrolysis yields the novel disaccharides.
