THIS method is regarded as the most promising yet adumbrated in that it reduces the problem of the synthesis of cholesterol or its stereoisomerides and analogous substances to the much simpler one of preparing a monocyclic and a bicyclic intermediate. It seems to be especially important that the double bond of cholesterol is placed by this synthetic process in the correct position and that unlike many other diene syntheses the method can be used to introduce the angle-methyl groups.
这种方法被认为是最有前途的,因为它将
胆固醇或其立体异构体和类似物质的合成问题简化为制备单环和双环中间体的简单问题。特别重要的是,
胆固醇的双键通过这种合成过程被放置在正确的位置,并且与许多其他二烯合成不同,该方法可用于引入角甲基。
