Bismuth(iii)-catalyzed regioselective alkylation of tetrahydroquinolines and indolines towards the synthesis of bioactive core-biaryl oxindoles and CYP19 inhibitors

Bismuth(iii)-catalyzed regioselective alkylation of tetrahydroquinolines and indolines have been demonstrated for the synthesis of the bioactive cores of biaryl oxindoles and CYP19 inhibitors.
