A series of 5,5-diaryl-2-thiohydantoins and 5,5-diaryl-N3-substituted-2-thiohydantoins related to 5,5-diphenyl-2-thiohydantoin (DPTH) were investigated as potential hypolipidemic agents with the goal of increased potency over DPTH itself. In the 5,5-diaryl class, the best results were obtained by substituting two pyridyl rings for the phenyl rings ...

Linear anhydrides are formed by the action of acetic anhydride on p-toluene-sulphonylglycine and carbobenzyloxy-glycine, -phenylalanine, and -β-alanine. The anhydrides from the first two acids yield the corresponding 2-thiohydantoin with ammonium thiocyanate in acetic acid. Other methods for the preparation of l-p-toluenesulphonylglycine anhydride, and

Synthesis of 3‐Ω‐Amino‐2‐thiohydantoins.
ChemInform, 2003AbstractIn the reaction of ethyl isothiocyanatoacetate with diamines, followed by cyclization of the intermediate product, 3‐monosubstituted thiohydantoins have been obtained. It was found that the reaction course depends on the purity of the isothiocyanate used and also, in the case of dialkylaminoamines, the self‐cyclization occurs.
