Rhodium(III)-catalyzed coupling between ketoximes and alkynes via C–H activation and annulation typically followed the[4+2]selectivity to afford isoquinolines.By designing alkynes bearing a highly electron-withdrawing group and under substrate control,we have successfully switched the selectivity of the coupling between oximes and alkynes to the alternative[3+2]annulation,leading to the efficient synthesis of indenamines.This process features good regioselectivity for both substrates,high efficiency,broad substrate scope,and excellent functional group tolerance.
