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 a 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 derivative adriamycin.
提供了一种新的合成某些杂环醌类化合物的方法。特别地,提供了一种新的、具有区域特异性的合成9-乙酰基-6,11-二羟基-4-甲氧基-7,8,9,10-四氢萘并-5,12-醌(7,9-二脱氧多柔比星醌)的方法,该化合物是多柔比星醌的合成中已知的中间体。同时,还提供了一种制备7,9-二脱氧多柔比星醌的类似物的方法,从而提供了制备多柔比星醌已知和所需类似物的方法。多柔比星醌是一种已知的化合物,是制备临床上已接受的自然产生的抗肿瘤抗生素多柔比星及其衍生物阿霉素的中间体。
