Eleven 5-substituted-2-thiohydantoin derivatives were synthesized by a two-step reaction of ammonium thiocyanate with α-amino acids under microwave irradiation. The structures of intermediate products and final products were characterized by 1H NMR, IR spectra and elemental analysis. Compared with conventional heating method, microwave irradiation possessed such advantages as short reaction time (4 min), high yield of each step (85%~93%). In the meantime, the reaction course of synthesis of compound 2h was discussed.

Key words: 5-substituted-1-acetyl-2-thiohydantoin, 5-substituted-2-thiohydantoin, ammonium thiocyanate, microwave irradiation, α-amino acid
