Treatment of diamides derived from α-amino acids with phosphorus pentasulfide or Lawesson's reagent was shown to provide a convenient method to prepare 5-aminothiazoles. By this method, in addition to monocyclic 5-aminothiazoles 19, novel bicyclic 5-aminothiazole derivatives such as 4,5,6,7-tetrahydrothiazolo[5,4-b]pyridines II, 5,6,7,8-tetrahydro-4H-thiazolo[5,4-b]azepines 7, 4,5,6,7,8,9-hexahydrothiazolo[5,4-b]azocine 16 and related compounds were prepared in moderate to good yields from simple diamides, suggesting the wide versatility of the method.
