3-Mercaptopropionic acid-nitrile imine adducts. An unprecedented cyclization into 1,3,4-thiadiazol-2(3H)-ones and -2(3H)-thiones

3-Mercaptopropionic acid-nitrile imine acyclic adducts (6a-c) undergo cyclocondensation with 1,1'-carbonyldiimidazole to afford the respective 1,3,4-thiadiazol-2-(3H)-ones (7a-c). Corresponding 1,3,4-thiadiazol-2(3AT)-thiones (8a-c) were likwise produced

Synthesis of Heterocycles. Part II. New Routes to Acetylthiadiazolines and Alkylazothiazoles

Methylglyoxalyl chloride arylhydrazones (III) react with an ethanolic solution of thiourea to give 2-amino-4-methyl-5-arylazothiazoles (XII) instead of the expected 2-acetyl-4-aryl-5-imino-Δ2-1,3,4-thiadiazolines (V) which were obtained from II
