A new two-step procedure that includes an initial regioselective intermolecular hydroaminoalkylation of ortho-chlorostyrenes with N-methylanilines and a subsequent intramolecular Buchwald–Hartwig amination gives direct access to 1,2,3,4-tetrahydroquinolines. The hydroaminoalkylation reaction of the ortho-chlorostyrenes is catalyzed by a 2,6-bis(phenylamino)pyridinato titanium complex which delivers the linear regioisomers with high selectivities. In addition, the formation of unexpected dihydroaminoalkylation products from styrenes and N-methylanilines is reported.
