An efficient synthesis of tetrahydrocarboline-type products and polycyclic spiroindolines has been achieved. The transformation proceeds via rhodium(II)-catalyzed intramolecular annulations of indolyl- and pyrrolyl-tethered N-sulfonyl-1,2,3-triazoles. The reaction could be tuned toward either the formal [3 + 2] cycloaddition or the C-H functionalization reaction depending on the electronic and structural features of the substrates, leading to the production of a variety of structurally related heterocyclic compounds.

An efficient Cu/Rh-catalyzed method is proposed for the synthesis of 3-indolylimines from N-propargylanilines through Rh(II)-catalyzed denitrogenative annulation of N-sulfonyl-1,2,3-triazoles. Further combined with hydrolysis or reduction, a one-pot method is developed to enable the direct incorporation of an imine, aldehyde, or amine group into an indole system from an alkyne. A variety of substituted 3-indolylimines, indole-3-carboxaldehydes, and 3-Indolylmethanamines are synthesized in good yields.
