Abstract

Herein, we disclose an efficient approach for the synthesis of unsymmetrical indolyl diketones from easily accessible 1,2-alkynediones involving a sequential aza-Michael addition/C–H Functionalization process. The two-step, one-pot strategy involves the aza-Michael addition of an aniline generating the N-aryl enaminones followed by iodine-mediated C–H functionalization.

通过氮杂迈克尔加成/C-H 官能化顺序,从乙烯酮模块化合成不对称吲哚基二酮
在此,我们揭示了一种从容易获得的 1,2-alkynediones 合成非对称吲哚基二酮的高效方法,该方法涉及一个连续的偶氮-迈克尔加成/C-H 功能化过程。这种两步一步法涉及苯胺与 N-芳基烯酮的偶氮-迈克尔加成,然后进行碘介导的 C-H 功能化。
