Visible-Light-Induced, Palladium-Catalyzed Annulation of 1,3-Dienes to Construct Vinyl N-Heterocycles

Herein, a photoinduced palladium-catalyzed annulation of 1,3-dienes with bifunctional halognated alkylamines has been developed, offering a facile route to access a broad range of vinylpyrrolidines. The reactivity profile of this protocol was able to be readily manipulated to assemble vinylpyrrolidine and vinlysilaazacycle. Remarkably, the utility of this strategy was further illustrated in the construction of complex and biologically important molecules as well as the diversity-oriented transformations of the resulting product.
