Benzyltrimethylammonium Dichloroiodate Catalyzed Four-Component Synthesis of Fully Functionalized Pyrroles Under Eco-compatible Conditions

摘要

Benzyltrimethylammonium dichloroiodate promoted an eco-compatible synthesis of fully functionalized pyrroles via isocyanide-based four-component reactions under solvent-free conditions that are reported. Benzyltrimethylammonium dichloroiodate supported reaction process including Knoevenagel condensation followed by the Michael type and intramolecular cyclization that gives high yields.
