Photolysis of 3-methylcholesta-3,5-diene (V) in ethanol gave 3-methylenecholest-5-ene (VI), 6β-ethoxy-3α-methyl-3β,5-cyclo-5β-cholestane (VII), 3β-ethoxy-3α-methylcholest-5-ene (VIII), and 3α-methylcholesterol (VIIIa) as well as a number of unidentified hydrocarbons and alcohols. A similar photolysis in pentane, followed by reaction of the resulting 3β,5;4α,6α-bicyclo-5β-cholestane (IIa) with ethanol
3-methylcholesta-3,5-diene (V) 在乙醇中的光解得到 3-methylenecholest-5-ene (VI), 6β-ethoxy-3α-methyl-3β,5-cyclo-5β-cholestane (VII), 3β -ethoxy-3α-methylcholest-5-ene (VIII) 和 3α-methylcholesterol (VIIIa) 以及一些不明的碳氢化合物和醇。在戊烷中进行类似的光解,随后生成的 3β,5;4α,6α-双环-5β-胆甾烷 (IIa) 与乙醇反应,得到环醚 VII 作为唯一可分离的产物。
