Catalyst-controlled enantioselective 1,1-arylboration of unactivated olefins

Enantioselective difunctionalization of alkenes constitutes an efficient strategy to assemble complex chiral molecules from simple racemic or achiral starting materials. Here we present an intermolecular nickel-catalysed enantioselective 1,1-arylboration of unactivated terminal alkenes. The high regio- and enantioselectivities of the reactions arise from a judicious choice of the nickel catalyst rather than the incorporation of a directing...
