Some novel chiral sulfonyl hydantoin derivatives 2a-e and 3 a-e have been prepared. p-Toluenesulfonyl chloride on treatment with L-amino acids in presence of K2CO3/H2O yielded N-(p-toluensulfonyl-)amino acids 1a - e which were cyclized in presence of NH4-SCN Ac2O to afford 1-(p-toluenesulfonyl)-5-substituted-2-thiohydantoins 2a-e. These compounds were oxidized with HNO3 to yield 1-(p-toluenesulfonyl)-5-substituted hydantoins 3a-e. The enantiomeric ratios of 3a-e were determined by 1H NMR spectroscopy using Eu(hfc)3. The antidiabetic activity of 3a-d has been determined.
