Abstract 5‐Butoxyhydantoin (2a), 3‐benzyl‐5‐methoxyhydantoin (2b) and 3‐ p ‐chlorophenyl‐5‐methoxy hydantoin (2c) were found to react, in the presence of an acid catalyst, with aromatic compounds and olefins to give 5‐arylhydantoin (3) and 5‐alkylhydantoins with an unsaturated side chain. Isomers which differ in the location of the double bond (4,5,6) as well as cis‐trans isomers were isolated and characterized.
