Herein, an N-heterocyclic carbene (NHC)-catalyzed tandem cyclization/addition/cyclization reaction of 2-isocyanobiaryls and α-bromo-N-cinnamylamides for the synthesis of 2-pyrrolidinone-functionalized phenanthridines is developed. This protocol features a radical cascade process, broad substrate scope, and good functional group compatibility under metal- and oxidant-free reaction conditions.
在此,开发了一种用于合成2-吡咯烷酮官能化菲啶的N-杂环卡宾(NHC)催化的2-异氰基联芳基与α-溴-N-肉桂酰胺的串联环化/加成/环化反应。该方法具有自由基级联过程、广泛的底物范围以及在无金属和无氧化剂的反应条件下良好的官能团兼容性。
