There is provided a novel method of synthesizing certain heterocyclic quinones. In particular there is provided a novel and regiospecific synthesis of 9-acetyl-6,11-dihydroxy-4-methoxy-7,8,9,10-tetrahydronaphthacene-5,12-quin one (7,9-dideoxydaunomycinone) which is known intermediate in the synthesis of daunomycinone. There is also provided a method of preparing analogs of 7,9-dideoxydaunomycinone which thus provide for the preparation of known and desired analogs of daunomycinone. Daunomycinone is a known compound which is an intermediate in the preparation of the clinically accepted naturally-occurring antitumor antibiotics daunomycin and its derivitive adriamycin.
