Reported herein are the Rh(III)-catalyzed cascade annulation reactions of N-(pivaloyloxy)benzamides with 1,5-enynes to access diversely substituted aromathecin derivatives involving C–H activation. The developed procedure offers an efficient synthetic tool for the assembly of a wide range of N-(pivaloyloxy)benzamides and 1,5-enynes with good atom economy and functional group tolerance. The key reactions
本文报道的是Rh(III)催化的N-(新戊酰氧基)苯甲酰胺与1,5-炔烃的级联环化反应,以得到涉及CH活化的各种取代的芳香族衍生物。所开发的程序为组装具有良好原子经济性和官能团耐受性的各种N-(新戊酰氧基)苯甲酰胺和1,5-烯炔提供了一种有效的合成工具。在无氧化剂温和反应条件下,这种环空反应的关键反应是炔烃插入和氮杂-迈克尔加成反应。
