The preparation of 13-methylgon-4-enes and novel 13-polycarbonalkylgon-4-enes by a new total synthesis is described. 13-Alkylgon-4-enes having progestational, anabolic and androgenic activities are prepared by forming a tetracylic gonane structure unsaturated in the 1,3,5(10),9(11) and 14-positions, selectively reducing in the B- and C-rings, and converting the aromatic A-ring compounds so-produced to gon-4-enes by Birch reduction and hydrolysis.
描述了通过新的全合成方法制备13-甲基孕-4-烯和新型13-聚碳烷基孕-4-烯。通过形成在1,3,5(10),9(11)和14-位置不饱和的四环孕烷结构,选择性地在B和C环中还原,并将所产生的芳香A环化合物转化为孕-4-烯,制备具有孕激素、合成激素和雄激素活性的13-烷基孕-4-烯。
