(±)-2,4-Dimethoxyoestra-1,3,5(10)-trien-17β-ol (7; R1= R3= OMe, R2= H), synthesized from 5,7-dimethoxy-1-tetralone (1), was found to be identical with the demethoxylated product obtained by metal–ammonia reduction of 2,3,4-trimethoxyoestra-1,3,5(10),8-tetraen-17β-ol (6; R1= R2= R3= Me).
由5,7-二甲氧基-1合成的(±)-2,4-二甲氧基oestra-1,3,5(10)-trien-17β-ol(7; R 1 = R 3 = OMe,R 2 = H) -四氢萘酮(1)被发现与通过金属-氨还原2,3,4-三甲氧基oestra-1,3,5(10),8-四烯-17β-醇(6; R 1 = R 2 = R 3 = Me)。
