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
