ChemInform Abstract: Synthesis of 5-Benzoyl-5-phenyl- and 5-Phenylhydroxymethyl-5-phenylhydantoins as Potential Anticonvulsants

A series of 5-benzoyl-5-phenyl- and S-phenyl-5-phenylhydroxymethylhydantoins have been synthesized from the reaction of urea, N-monosubstituted ureas and sym-N-N-disubstituted ureas with phenyltriketone hydrate, via a pinacol-pinacolone-type rearrangement mechanism. The compounds were evaluated for anti-convulsant activity in mice.
