摘要：

A highly enantioselective (up to 94 % ee) alkylation of cyclic allyl phenyl ethers with Grignard reagents catalyzed by nickel complexes of C2-symmetric chiral diphosphine ligands is described; for the ligands related to (+)-(R,R)-cyclopentane-1,2-diylbis(diphenylphosphine) the enantioselectivity of the reaction appears to be influenced much more by steric than by electronic factors, which, however, strongly affect the chemoselectivity of the process.
