This paper reports the kinetic resolution of racemic secondary alcohols (O-nucleophiles) via stereoselective intramolecular allylic substitution. The reaction was enabled by synergistic palladium and chiralphosphoricacidcatalysis and produced chiral cis-1,3-disubstituted 1,3-dihydroisobenzofurans with a selective factor of up to 60.9 and a diastereomeric ratio of up to 7.8:1. Asymmetric synthesis
