The first enantioselectivecopper-catalyzedconjugateaddition of α-substituted benzyl nitriles to alkyl acrylates is described. This protocol allows the direct and 100% atom-economic generation of a nitrile-containing quaternarystereogeniccenter in a highly enantioselective manner. The practical application of our methodology was demonstrated through the concise formal synthesis of (−)-aphanorphine

operationally simple three-component coupling reactions involving arynes, phosphites, and acrylates have been achieved. The reaction proceeded well with α- or β-substituted acrylates. Additionally, various functional groups were tolerated under these reactionconditions, resulting in diverse ortho-3-propanoate-substituted aryl phosphonates. Moreover, the reaction can be used to synthesize a range of organophosphorus
