The asymmetric allylic substitution of allyl phosphates with aryl- and alkenylboronates catalyzed by a copper/N-heterocyclic carbene complex was developed and the γ-substitution products were obtained with high enantioselectivity (see scheme). To account for the observed influence of the reaction parameters a possible catalytic cycle for this process was proposed.
