The syntheses of the title compounds were accomplished by Koenig-Knorr condensation of acylated furanoses with digitoxigenin followed by basic hydrolysis of protecting groups. In this manner the riboside, 5-amino-5-deoxyriboside, 3,6-anhydroglucoside, and 3,6-dideoxy-3,6-iminoglucoside of digitoxigenin were prepared. These compounds as well as several of the synthetic intermediates showed weak to moderate cardiotonic activity.
