An efficient MgI2-catalyzed annulation between donor–acceptor cyclopropane and N-tosylaziridinedicarboxylate to access highly substituted 2H-furo[2,3-c]pyrrole bearing two rings and four stereocenters, including one quaternary carbon stereocenter, has been developed. This methodology can be used for the synthesis of biologically active compounds like IKM-159. This work also offers an insight into the
已经开发了一种有效的MgI 2催化的供体-受体环丙烷与N-甲苯磺酰基叠氮基二羧酸酯之间的环合反应,以访问带有两个环和四个立体中心(包括一个季碳立体中心)的高度取代的2 H-呋喃[2,3- c ]吡咯。该方法可用于合成诸如IKM-159的生物活性化合物。这项工作还提供了对环化过程机制的见解。
