Palladium(0)‐Catalyzed Enantioselective CH Arylation of Cyclopropanes: Efficient Access to Functionalized Tetrahydroquinolines

Activated: The title reaction proceeds efficiently with 1 mol % of palladium and gives tetrahydroquinolines in excellent enantioselectivities (see scheme). The enantiodiscriminating concerted metalation–deprotonation step occurs via a rare seven-membered palladacycle. The cyclopropyl-substituted tetrahydroquinolines can be regioselectively and enantiospecifically reduced to chiral tetrahydrobenzoazepines.
