This report describes a one-pot synthesis of multisubstituted dihydroquinoxalin-2-ones using an umpolung N-alkylation followed by oxidation and C-alkylation reactions. Moreover, the synthesis of tricyclic compounds containing a dihydroquinoxaline skeleton was carried out by ring closing metathesis (RCM) of the resulting N,C-bis-addition products containing olefins.
本报告描述了使用 umpolung N-烷基化,然后是氧化和 C-烷基化反应的多取代二氢喹喔啉-2-酮的一锅合成。此外,含有二氢喹喔啉骨架的三环化合物的合成是通过所得含有烯烃的 N,C-双加成产物的闭环复分解 (RCM) 进行的。
