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.

A tertiary phosphine compound of the formula (1): STR1 wherein R1 and R2 represent independently from each other a hydrogen atom or a methyl group, or together form --CH=CH--CH=CH--; R3 is a hydrogen atom or a cycloalkyl group having 5 to 7 carbon atoms or a lower alkyl group which may be substituted with a halogen atom, a lower alkoxy group, a lower alkoxyalkoxy group or a phenyl group; X1 is a halogen atom when both R1 and R2 are hydrogen atoms, or a hydrogen atom, a halogen atom, a lower alkyl group or a lower alkoxy group when at least one of R1 and R2 is not a hydrogen atoms; and m is an integer of 1 to 5, which is useful as a ligand of a transition metal complex that can catalyze various reactions.
