Construction of Quaternary Stereogenic Carbon Centers through Copper‐Catalyzed Enantioselective Allylic Alkylation of Azoles

Copper‐catalyzed enantioselective allylic alkylation of azoles with γ,γ‐disubstituted primary allylic phosphates was achieved using a new chiral N‐heterocyclic carbene ligand bearing a naphtholic hydroxy group. This reaction occurred with excellent branch regioselectivity and high enantioselectivity, thus forming a controlled all‐carbon quaternary stereogenic center at the position α to the heteroaromatic ring.
