There is provided a novel method of synthesizing certain 3-(2',5'-dialkoxy- 4'-substituted phenyt) phthalides wherein the 4-substituent has para-directing properties. These compounds provide a novel and regiospecific synthesis of a 9-acetyl-6, 11-dihydroxy-4-methoxy- 7,8,9,10-tetrahydronaphthacene-5, 12-quinone (7,9- dideoxydaunomycinone) in particular, which is a known intermediate in the synthesis of daunomycinone. There is also provided a method of preparing analogs of 7,9- dideoxydaunomycinone. 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.
本发明提供了一种合成某些 3-(2',5'-二烷氧基-4'-取代苯基)邻苯二甲酸盐的新方法,其中 4-取代基具有对位定向特性。这些化合物为 9-乙酰基-6,11-二羟基-4-甲氧基-7,8,9,10-四氢萘-5,12-醌(7,9-二脱氧戴诺霉素酮)提供了一种新颖的特异性合成方法,尤其是合成戴诺霉素酮的已知中间体。此外,还提供了一种制备 7,9- 二脱氧达诺霉素酮类似物的方法。daunomycinone 是一种已知化合物,是制备临床上公认的天然抗肿瘤抗生素 daunomycin 及其衍生物 adriamycin 的中间体。
