The synthesis of steroidal heterocycles containing the pyrazole and pyrimidine ring fused to the 16,17-position of the steroid nucleus is reported. Androstenolone acetate (1) reacted with carbon disulfide, iodomethane and sodium hydride to furnish 3β-acetoxy-16-[bis(methylthio)methylene]-5-androst-5-en-17-one (2). The reactions of 2 with hydrazine hydrate and methylhydrazine afforded the 5’-methylthio-
据报道,合成了含有与类固醇核的 16,17 位稠合的吡唑和嘧啶环的类固醇杂环。雄甾烯醇乙酸酯 (1) 与二硫化碳、碘甲烷和氢化钠反应,得到 3β-乙酰氧基-16-[双(甲硫基)亚甲基]-5-androst-5-en-17-one (2)。2 与水合肼和甲基肼的反应分别得到 5'-甲硫基-吡唑并[4',3':16,17]androst-5-en-3β-ols 3a 和 3b。在甲醇钠存在下用脒、胍和异硫脲盐处理 2 产生 6'-甲氧基-嘧啶[5',4':16,17]androst-5-en-3β-ols (4a-4e) .
