An unprecedented rhodium-catalyzed regioselective C-H activation/1,8-diazabicyclo[5.4.0]undec-7-ene-catalyzed intramolecular amidation of 7-arylindoles with diazomalonates is described that provides a straightforward route to seven-membered azepino[3,2,1-hi]indoles in good to excellent yields in one pot. A wide range of functional groups, including F, OMe, NPh2, SiMe3, Cl, CN, CHO, COMe, CO2Me, CF3
前所未有的铑催化的区域选择性CH活化/ 1,8-二氮杂双环[5.4.0]十一碳-7烯催化的7-芳基吲哚与重氮丙二酸酯的分子内酰胺化反应为七元azepino [3,2]提供了直接途径一锅中,1-1-吲哚的产率良好至优异。包括F,OMe,NPh2,SiMe3,Cl,CN,CHO,COMe,CO2Me,CF3和NO2在内的各种官能团均具有良好的耐受性。
