【摘要】 13β-乙基-3-甲氧基-甾-1,3,5(10),9(11)-四烯-17β-醇(Ⅰ)经硼氢化氧化,除主要产物112α-羟基物(Ⅱ)外,还分离得到11β-羟基物(Ⅲ),9β-氢-11α-轻基物(Ⅳ),9α-羟基物(Ⅴ)和9α-羟基物(Ⅵ)。(Ⅳ),(Ⅴ)和(Ⅵ)为新化合物。更多还原

【Abstract】 Five compounds were obtained and identified from the hydroboration of 13β-ethyi-3-methoxygona-1,3,5(10), 9(11)-tetraene-17β-ol(Ⅰ), among which four compounds were isolated here for first time.Compounds (Ⅳ)——(Ⅵ) were three new compounds. Their structures were elucidated by means ofspectral methods as 9β-H-11α-hydroxyl(Ⅳ), 9α-hydroxyl(Ⅴ) and 9β-hydroxyl(Ⅵ) respectively.更多还原
