Article abstract of DOI:10.1248/cpb.45.1

Upon irradiation of mono-, di-, and trithiobarbiturates in the presence of alkenes, [2 + 2]cycloaddition occurred regioselectively to give thietanes and their desulfurized products. In the case of trithiobarbiturate, a novel type of ring contraction product, dithiohydantoin, was also obtained.
