Electrochemical Cascade Cyclization Reactions of Nitrosobenzenes in Construction of Quinolines and Pyrroles
A novel electrochemical cascade cyclization between nitrosobenzene and electron-deficient alkynes was developed in this work.The use of electroreduction for the activation of nitrosobenzene which highlighted the unique possibilities associ-ated with electrochemical activation methods.This protocol represents a simple,efficient,and environmentally benign way to construct substituted quinolines and pyrroles in good yields with high selectivity.
