Iodine‐Catalysed Reactions of Aroylmethylidenes: Efficient Access to α‐Substituted Aryl Ketones, Functionalized Naphthofurans and Highly Functionalized Pyrroles

Abstract

AbstractAn efficient and facile iodine‐catalysed approach has been established for the formation of α‐substituted aryl ketones and valuable substituted naphthofurans. Under the same reaction conditions, a series of highly functionalized pyrroles could be readily obtained. This metal‐free and environmentally friendly reaction proceeded very well and delivered the products in good to excellent yields. This work highlights the formation of α‐substituted aryl ketones, naphthofuran and pentasubstituted pyrrole derivatives under catalytic amount of iodine in one‐pot fashion, demonstrating the broad substrate scope.
