Stereocontrolled synthesis of (−)-de-AB-8-oxa-cholest-14-en-9-one (2) as an optically active form was achieved starting from the methylene ketone (7). This work constitutes a formal synthesis of de-AB-cholestan (1).
从亚甲基酮(7)开始实现立体控制合成(-)-de-AB-8-oxa-cholest-14-en-9-one(2)的旋光形式。这项工作构成了de-AB-cholestan(1)的正式合成。
