4aβ-trimethyl-1,2,3,4aβ,9,10,10aβ-octahydrophenanthrene (5, a skeletal representative of several diterpenes, has been synthesised stereoselectively through reductive methylation of the ∝,β-unsaturated ketone 14 in anhydrous ammonia followed by Huang-Minlon reduction.
7-甲氧基-1,1,4aβ-三甲基-1,2,3,4aβ,9,10,10aβ-八氢菲(5是几种二萜的骨架代表,已通过∝,β-的甲基化还原选择性地立体合成在无水氨中形成不饱和酮14,然后进行黄-米隆还原。
