The Use of Carbon Monoxide and Imines as Peptide Derivative Synthons: A Facile Palladium-Catalyzed Synthesis ofα-Amino Acid Derived Imidazolines

Abstract

One of the most facile routes to prepare carboxylate-substituted imidazolines is by the palladium-catalyzed coupling of an imine, carbon monoxide, and an acid chloride. In this reaction, a peptide unit is constructed and directly incorporated into the heterocyclic core.
