Abstract
Hydantoin ring formation via carbanilide cyclization is achieved in high yield with short reaction time by employing catalytic amounts of Ba(OH)2 (anhydrous or octahydrate) in DMF under microwave irradiation. Evidence is provided that kinetic product 4 (trans, anti, cis stereochemistry) epimerizes to thermodynamic product 3 (trans, anti, trans stereochemistry).
