  Construction of Highly Functional Quaternary Carbon Stereocenters via an Organocatalytic Tandem Cyanation–Allylic Alkylation Reaction

  摘要：

  The first tertiary amine-catalyzed tandem cyanation-allyic alkylation (CAA) reaction of aldehydes, appropriate cyanide sources, and Morita-Baylis-Hillman (MBH) adducts has been developed, which provides a facile access to densely functionalized products containing O-substituted quaternary centers.
