Abstract: Triple‐purpose protic ionic liquids were employed as a solvent, a Brønsted acid catalyst, and a source of the nucleophile (thiocyanate‐ion) for the chemodivergent transformation of dihydroimidazolones into 2‐thioxohexahydro‐5H‐imidazo[4,5‐d]oxazol‐5‐ones and tetrahydro‐2H‐imidazo[4,5‐d]thiazole‐2,5(3H)‐diones. An important feature of this… read more here.
