Novel Ring-Opening Reactions of 3-Substituted 1-Amino-2-thioxo-4-imidazolidinones: Preparation of Functionalized 3,6-Dihydro-2H-1,3,4-thiadiazines and 3,4-Dihydro-1H-1,2,4-triazoles

1-Amino-2-thioxo-4-imidazolidinones 1 react with phenacyl bromides to yield 3-alkoxycarbonylmethyl-5-aryl-2-iminio-3,6-dihydro-2H-1,3,4-thiadiazine salts 3.Compounds 1 also react with aryl isothiocyanates to give N-aryl-N'-(3-aryl/alkyl-4-oxo-2-thioxoimid
