Domino Reactions Based on Combinatorial Bond Transformations in Electron-Deficient Tertiary Enamines

Electron-deficient enamines such as enaminones and enaminoesters are moieties showing widespread application in organic synthesis. Among the various available electron-deficient enamines, the N,N-disubstituted amino-functionalized ones (tertiary enamines) represent a class of special enamines with distinct properties and important applications. Based on our longstanding interest in exploring novel synthetic methods using electron-deficient tertiary enamines, we present herein the research advances in organic synthesis via domino reactions making use of the combinatorial C-N, C=C, C-H, and other bond transformations of electron-deficient tertiary enamines.
