Abstract An efficient Rh(III)‐catalyzed C−H bond activation/cyclization of 2‐arylbenzimidazoles with CF 3 ‐imidoyl sulfoxonium ylides has been achieved, yielding diverse − and amino‐disubstituted 5,6‐dihydrobenzoimidazo[2,1‐ a ]isoquinolines, which could undergo deaminative hydroxylation to access hydroxy‐disubstituted ]isoquinolines catalyzed by Sc(OTf) . This developed strategy features easily available starting materials, broad substrate scope, good scalability high efficiency. Moreover, the antitumor activities selected products against some human cancer cell lines were also investigated, results indicated that several show antiproliferative activities.

A condition-controlled Rh(III)-catalyzed selective synthesis of CF3-substituted indoles and pyrido[2,1-a]isoindoles from 2-arylpyridines CF3-imidoyl sulfoxonium ylides has been developed. The Cp*Rh(MeCN)3(SbF6)2/HFIP system afforded via triple C–H activation, while the [Cp*RhCl2]2/MeCN condition selectively furnished through [4 + 1] annulation. notable advantages this developed method included readily available starting materials, broad substrate scope, excellent chemoselectivity. Importantly, several selected products showed promising antitumor activities.
