Abstract

A robust and operational simple route to 2,4-disubstituted pyrrole heterocycles relying upon a cascade reaction is air and moisture tolerant and is performed at ambient temperature. Control over the reaction conditions provides ready access to isopyrroles, 2,3,4-trisubstituted pyrroles and 3-substituted pyrollidin-2-ones.
