摘要
A new class of chiral spirocyclic borate ligands 5a-d with a rigid borocycle has been developed. The catalyst formed from chromium(II)-5a promotes the highly efficient enantioselective Nozaki-Hiyama allylation of alkyl and aryl ketones using allyl bromide. ne scope of the present method is shown to be wide, and it affords an efficient access to chiral tertiary homoallylic alcohols.
