Enantioselective synthesis of α-tri- and α-tetrasubstituted allylsilanes by copper-catalyzed asymmetric allylic substitution of allyl phosphates with silylboronates
A copper/N-heterocyclic carbene-catalyzed asymmetric allylic substitution of allyl phosphates with a silylboronate has been developed to give highly enantioenriched allylsilanes. High regioselectivity has been achieved by employing NaOH as the base, and this catalyst system is effective for both γ-mono- and disubstituted allyl phosphates.
