Herein, we present a new annulation reaction of quinolinium salts with indoles and paraformaldehyde, which enables syn-diastereoselective construction of a vast range of fused tetrahydroquinolines via ruthenium-catalyzed hydride-transfer-initiated tandem functionalization of the quinoline skeleton. The developed transformation proceeds with mild reaction conditions, good substrate and functional group
