A resin acid, (+)-dehydroabietic acid, was converted into 3,4,4a,9,10,10a-hexahydro-7-methoxy-10aβ-methyl-4aαH-phenanthren-1(2H)-one (2) by the introduction of oxygen functions at the C-4 and C-13 positions, and a rearrangement of the angular methyl group to the C-5 position. The hydrophenanthrene derivative 2 was further transformed into 2,3,3a,4,5,9b-hexahydro-7-methoxy-3aβ-methyl-9bαH-1H-benz[e]inden-3β-ol
树脂酸,(+)-脱氢松香酸,被转化为 3,4,4a,9,10,10a-六氢-7-甲氧基-10aβ-甲基-4aαH-菲-1(2H)-one (2)在 C-4 和 C-13 位置引入氧功能,并将角甲基重排到 C-5 位置。氢菲衍生物 2 进一步转化为 2,3,3a,4,5,9b-六氢-7-甲氧基-3aβ-甲基-9bαH-1H-benz[e]inden-3β-ol (3)。由于已经报道了 3 转化为甾体激素,因此目前的合成可以看作是由 (+)-脱氢松香酸合成甾体激素。
