With an unactivated double bond as the radical acceptor, allyl amines underwent a metal-free trifluoromethylation/cyclization cascade with CF3SO2Na (Langlois’ reagent), affording CF3CH2-containing indolines and tetrahydroisoquinolines, whose practical syntheses are significant challenges. This protocol features mild conditions, low cost, and a broad substrate scope.
烯丙基胺以未活化的双键作为自由基受体,与CF 3 SO 2 Na(Langlois试剂)进行了无金属的三氟甲基化/环化级联反应,从而提供了包含CF 3 CH 2的二氢吲哚和四氢异喹啉,它们的实际合成面临重大挑战。该协议具有条件温和,成本低和基材范围广的特点。
