Synthesis ofiImidazolidinone, imidazolone, and Benzimidazolone Derivatives through oxidation using copper and air

Authors: Li, DazhiOllevier, Thierry
Abstract: A new synthetic method of urea derivatives using copper and air was developed. These mild conditions provided moderate to very good yields for 15 examples (53–93%), while low yields were obtained with sterically hindered substrates (3 examples). The reaction was found to go through an in situ-generated copper-N-heterocyclic carbene, which is then oxidized into cyclic urea derivatives possessing alkyl, benzyl, aryl, hydroxy, Boc-protected, and tertiary amine groups
