Photoredox Catalyzed Cyclization of Enaminones/Ketene N,S‑Acetals with β‑Ketodinitriles to Access Polysubstituted Pyrroles

A facile synthesis of polyfunctionalized pyrroles has been explored via photoredox cascade cyclization of enaminones/ketene N,S-acetals with β-ketodinitriles using eosin Y, CuI, and Ag2CO3 in acetonitrile under blue...
