A facile method for the regioselectivesynthesis of tetrasubstituted pyrroles, from readily accessible 1,3-dicarbonyls, benzoin derivatives and ammonium acetate, has been developed. The one-potthree-component reactions were performed to afford tetrasubstituted pyrroles under solvent- and catalyst-freeconditions.

Pyrroles, ubiquitous bioactive heterocycles in nature, are readily prepared via a palladium‐catalyzedoxidative annulation of cyclic trans‐enamines to various internal alkynes in the absence of a directing group.
