TBADT-Photocatalyzed Trifluoromethylation of Phenylpropiolamides Using Langlois Reagent: Access to Oxindole Derivatives

bond (via a Michael addition on the propiolamide moiety), followed by an intramolecular C-C bond formation and reduction sequence. Thus, a broad range of trifluoromethyl-substituted oxindoles have been accomplished in high yields under mild conditions.
