Pd-catalyzed chemo-, regio-, and enantioselective ring-closing/ring-opening cross couplingreaction has been developed with diverse aryl halide-tethered alkenes and benzocyclobutenols as substrates, which renders the highly enantioselective diarylation of unactivated alkenes and provides a convenient method toward chiral 2,3-dihydrobenzofurans bearing a quaternary stereocenter with excellent enantioselectivities

Catalytic construction of oxindoles bearing all-carbon-quaternary centers attracts wide attention from the synthetic chemistry community. Herein, we report a palladium-catalyzed sequential Heck coupling/C–C bond activation of aryl halide-tethered alkenes with benzocyclobutenols affording a series of oxindole-derived compounds in good to excellent yields, as well as the preliminary enantioselectivity
