Dianionic enolates formed from N′-aryl urea derivatives of amino acids undergo intramolecular C-arylation by attack of the enolate anion on the N′-aryl ring, leading to a hydantoin derivative of a quaternary amino acid. In situ IR studies allow identification of four intermediates on the reaction pathway.
