The first synthesis of new doxorubicin and daunomycin analogs containing glucuronic acid moieties instead of daunosamine are described. The desired products, daunomycinone-7-D-glucuronide (DM7G, 10) and doxorubicinone-7-D- glucuronide (DX7G, 11) were conveniently prepared through the glycosylation at 7-hydroxyl group of daunomycinone (4) or 14-acetoxydoxorubicinone (6) with glucuronic acid derivative 7 by the Koenigs-Knorr procedure followed by alkaline deacetylatipn using aqueous LiOH solution and amberlite cation exchange material. The anomeric configuration and conformation of all products were fully characterized by assignment of 1H NMR chemical shifts and H-H coupling constants based on reported literatures.
