The irradiation of 6-methylcholest-5-en-3β-ol in benzene containing mercury(II) oxide and iodine gave 3α,5-epoxy-6-methylene-A-homo-4-oxa-5α-cholestane (23%) and 2-iodo-6-methyl-A-nor-2,3-secocholest-5-en-3-yl formate (32%). The thermally-induced reaction at 55–60 °C gave the former in a 16% yield. The corresponding photo-reaction of 4,4,6-trimethylcholest-5-en-3β-ol, however, gave 4,6-dimethyl-4-methylene-3,4-secocholest-5-en-3-al.
在含有氧化
汞(II)和
碘的苯中辐照 6-甲基胆甾烯-5-烯-3β-醇,可得到 3α,5-环氧-6-亚甲基-A-高-4-氧杂-5α-胆甾烯(23%)和 2-
碘-6-甲基-A-去甲-2,3-苯并胆甾烯-5-烯-3-
甲酸酯(32%)。在 55-60 °C的热诱导反应中,前者的产率为 16%。而 4,4,6-三甲基-
5-胆甾烯-3β-醇的相应光反应则生成了 4,6-二甲基-4-亚甲基-3,4-secocholest-5-烯-3-al。
