  It is an object of the present invention to provide a novel method for producing a steroid compound. The present invention provides a method for producing 5β-3,7-dioxocholanic acid or an ester derivative thereof, using, as a raw material, a sterol having double bonds at position 5 and at position 24, such as cholesta-5,7,24-trien-3β-ol, ergosta-5,7,24(28)-trien-3β-ol, desmosterol, fucosterol, or ergosta-5,24(28)-dien-3β-ol, via the following 4 steps: (I) a step involving oxidation of a hydroxyl group at position 3 and isomerization of a double bond at position 5 to position 4; (II) a step involving the oxidative cleavage of a side chain to convert position 24 to a carboxyl group or an ester derivative thereof; (III) a step of introducing an oxygen functional group into position 7; and (IV) a step of constructing a 5β configuration by reductive saturation of a double bond at position 4.

  本发明的目的是提供一种新型类固醇化合物的制备方法。本发明提供了一种以具有5号和24号位置双键的类固醇（如胆甾-5,7,24-三烯-3β-醇、麦角甾-5,7,24(28)-三烯-3β-醇、脱甾醇、褐藻甾醇或麦角甾-5,24(28)-二烯-3β-醇）为原料，通过以下4个步骤制备5β-3,7-二氧代胆甾酸或其酯衍生物：(I) 氧化3号羟基并异构化5号双键至4号的步骤；(II) 氧化断裂侧链以将24号位置转化为羧基或其酯衍生物的步骤；(III) 在7号位置引入氧功能团的步骤；和(IV) 通过还原饱和4号位置的双键构建5β构型的步骤。
