A novel and simple approach for the preparation of 3-substituted, 5-substituted, or 3,5-disubstituted hydantoins is reported. It involves the reaction of α-amino methyl ester hydrochlorides with carbamates to yield the corresponding ureido derivatives, which subsequently cyclize under basic conditions to produce substituted hydantoins in good yields. By applying this method, the bioactive anticonvulsant
