Photochemical Transformation of Trithiobarbiturate into Thiohydantoin and Imidazolinothiophene Derivatives
摘要:
Upon irradiation of trithiobarbiturate (1), ring contraction reaction occurred to give thiohydantoin (2 or 3) and imidazolinothiophene (4) derivatives. Further, on treating with iodine, the thiohydantoins (2 and 3) undergo ring closure, giving imidazolinothiophene derivatives (4).
