Organophotocatalytic Carbamoylation of Morita‐Baylis‐Hillman Carbonates

Herein, we demonstrate that carbamoyl radicals generated through an organophotocatalytic protocol from 4-carbamoyl-dihydropyridines (carbamoyl-DHPs) can be incorporated into Morita-Baylis-Hillman (MBH) carbonates, affording a range of polyfunctionalized scaffolds with yields ranging from 63–98%. Reaction monitoring experiments, scale-up, reuse of the organophotocatalyst, and the hydrogenation of the succinamic ester's alkene moiety was also conducted, in order to showcase the mechanistic features and the robustness of this photochemical protocol.
