A stereoselective synthesis of the LM-ring fragment has been achieved starting from a sugar derivative. A stereoselective synthesis of the JKLM-ring fragment has been achieved through a coupling between two segments via heteroconjugate addition, seven-membered ether ring formation mediated by an acetylene cobalt complex, and spiroketalization reaction.
从糖衍生物开始已经实现了LM-环片段的立体选择性合成。JKLM环片段的立体选择性合成是通过两个部分之间的偶联实现的,包括异源共轭物加成,乙炔钴络合物介导的七元醚环形成以及螺酮缩合反应。
