Abstract
Upon irradiation of mono-, di-, and trithiobarbiturates in the presenc e of alkenes, [2+2]cycloaddition occurred regioselectively to give thi etanes and their desulfurized products. In the case of trithiobarbitur ate, a novel type of ring contraction product, dithiohydantoin, was al so obtained.
