The title compound (7), the 3'-acetoxy-4'-O-acetyl analog of adriamycin (doxorubicin), was synthesized in approximately 50% net yield from daunomycinone by bromination at C-14, glycosylation of the product at O-7 with 3,4-di-O-acetyl-2,6-dideoxy-alpha-L-l

A process for the synthesis of adriamycin and 7,9-epiadriamycin, both active antineoplastic agents, in which 7-deoxydaunomycinone, in either the 9s or racemic (±) form, is employed as the starting material, the process in one embodiment also being productive of the useful intermediate compound 4-methoxy-6,11-dihydroxy-7,8-dihydro-5,9(10H),12-naphthacenetrione. The process involves converting 7-deoxydaunomicinone successively to daunomycinone, adriamycinone, 14-0-p-anisyldiphenylmethyladriamycinone and finally to adriamycin or to both adriamycin and 7,9-epiadriamycin. When producing the latter mixture of diastereomers, the 7-deoxydaunomycinone starting material is first converted to racemate form by a process involving the successive production of 7-deoxydaunorubicinol, 4-methoxy-6,11-dihydroxy-7,8-dihydro-5,9(10H), 12-naphthacenetrione, (±)-4-methoxy-9-cyano-6,9,11-trihydroxy-7,8,9,10-tetrahydro-5,12-naphthacenedione, (±)-4-methoxy-9-cyano-9-(2'-tetrahydropyranyloxy)-6,11-dihydroxy-7,8,9,10-tetrahydro-5,12-naphthacenedione and (±)-7-deoxydaunomycinone.
