Synthesis of a range of 1,2,4-triazolin-5-ones has been carried out by thermally induced cyclization of 1-aryl/alkyl-2-alkyl isothiobiureas 4. The required isothiobiureas were generated in situ by the reaction of alkyl halides with 1-aryl/alkyl-2-thiobiureas 3 in acidic medium at reflux. The reaction proceeds after S-alkylation of the thiobiureas and is demonstrated by the isolation of the alkyl isothiobiurea intermediates and their subsequent acid catalyzed thermal cyclization.
SYNTHESIS AND REACTIONS OF 3-AMINOTHIAZOLIDINE-2-THION-4-ONE DERIVATIVES. 1. CONVERSION OF 3-AMINOTHIAZOLIDINE-2-THION-4-ONE DERIVATIVES TO SUBSTITUTED MERCAPTO-1,3,4-THIADIAZOLES

The corresponding carboxymethylthiothiadiazoles are formed by the action of formic acid on 3-aminorhodanine and 3-(3-phenylthioureido)rhodanine, and the action of rhodanineaniline on 3-(3-phenylthioureido)rhodanine leads to 2-anilino-5-carboxymethylthioth
