relationship of a novel class of aromatase inhibitors, C(19) steroids having no oxygen function at C-3, we tested aromatase inhibition activity of polar diol compounds 4,19-dihydroxyandrost-5-en-17-ones (25 and 27) and 6,19-dihydroxyandrost-4-en-17-ones (36 and 37). 4alpha,19-Diol 25 was synthesized from tert-butyldimethylsilyoxyandrost-4-ene steroid (9) through its OsO(4) oxidation, giving the 4alpha,5alpha-dihydroxy
作为我们对一类新型芳香酶抑制剂C(19)类固醇在C-3处无氧功能的构效关系的研究的一部分,我们测试了极性二醇化合物4,19-dihydroxyandrost-5-的芳香酶抑制活性en-17-ones(25和27)和6,19-dihydroxyandrost-4-en-17-ones(36和37)。由叔丁基二甲基甲硅烷氧基雄烷-4-烯类固醇(9)通过其OsO(4)氧化合成4alpha,19-Diol 25,得到4alpha,5alpha-dihydroxy衍生物12作为关键反应。乙酰化5beta,6alpha-dihydroxy-19-acetate 30及其5alpha,6beta-analogue 31,然后用SOCl(2)脱水和碱性羟基化分别得到6alpha,19-二醇36和6beta-异构体37。化合物(25)的C-4处的羟基的立体化学和化合物36和37的C-6处的羟基的立体化学分别基于(1)H
