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

A facile synthesis of polyfunctionalized pyrroles has been explored via photoredox cascade cyclization of enaminones/ketene <i>N</i>,<i>S</i>-acetals with β-ketodinitriles using eosin Y, CuI, and Ag<sub>2</sub>CO<sub>3</sub> in acetonitrile under blue...
