A mild procedure for C-7-selective C–H alkenylation of various indolines under oxidative palladium(II) catalysis is reported. A fully substituted urea, formed by carbamoylation of the indoline nitrogen atom, functions as a directing group. Both α,β-unsaturated acceptors and styrenes participate in this direct C–H functionalization. With a free NH group at the urea terminus, the nitrogen atom subsequently
Indoles, indolines and hydronaphthylamines are ubiquitous structural motifs in natural products, pharmaceuticals, and biologically active molecules. In this paper, we report the synthesis of aminodihydronaphthyl-substituted indoles and indolines via a Ru-catalyzed carbamoyl-directed C–H functionalization of indoles and indolines with 7-azabenzonorbornadienes. In the presence of Cu(OAc)2 and AgSbF6
