Metal-catalyzed alkene arylalkoxylation is a powerful complexity-building strategy for the synthesis of oxygen heterocycles from simple y-unsaturated alcohols,but only a few examples of catalytic enan-tioselective methods exist.Herein,an efficient palladium-catalyzed enantioselective arylalkoxylation ofγ-hydroxyalkenes with aryl halides is reported.The salient features of this transformation include a re-markable broad substrate scope,mild reaction conditions,and good functional group tolerance,delivering a series of chiral tetrahydrofurans containing a tertiary or quaternary stereocenter in good yields with up to 95％ee.The Xu10 ligand with a suitable side-arm was responsible for the high reactivity and good enantioselectivity of this transformation.
