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.
本文描述了一种新的全合成方法,制备了13-甲基gon-4-烯和新型的13-聚碳烷基gon-4-烯。通过形成一个在1,3,5(10),9(11)和14-位不饱和的四环戊烷骨架,选择性地在B环和C环中还原,然后通过Birch还原和水解将产生的芳香A环化合物转化为gon-4-烯,制备了具有孕激素、增强剂和雄激素活性的13-烷基gon-4-烯。
