The pteridin-2,4,7-trione 6,8'-endoperoxides are synthesized and their thermal reactions are examined.The pteridin-2,4,7-triones (1) reacted smoothly with singlet oxygen to yield the pteridin-2,4,7-trione 6,8'-endoperoxides (2-5).On warming the endoperoxide (2a) reverted to the starting pteridin-2,4,7-trione (1a) with liberation of singlet oxygen, which was confirmed by trapping experiment using typical singlet oxygen acceptors (7-12).

Imidazolin-2-ones(13-18) on photooxygenation in the presence of methylene blue yielded the corresponding diacylureas as the only products isolated at room temperature. The rate of photooxygenation followed the order 16>17>18>13>14>15. The reaction was als
