Reaction pathway for the formation of the hydrogen chloride adducts of pyrimidosemibullvalene-2,4-dione derived from the photoreaction of 6-chloro-1,3-dimethyluracil in frozen benzene is interpreted by the mechanism involving the initial ortho-cycloaddition, not meta-cycloaddition, followed by the photochemical disrotatory cleavage of the cyclobutene moiety, and the successive intramolecular photo-Diels-Alder reaction of the resulting cyclooctatetraene ring.
Synthesis of cyclooctapyrimidine-2,4-diones by photocycloaddition of 6-chloro-1,3-dimethyluracil to benzenes in the presence of trifluoroacetic acid

Photoreaction of 6-chloro-1,3-dimethyluracil in benzene and monosubstituted benzenes furnished cycloaddition products, cyclooctapyrimidine-2,4-dione derivatives, in the presence of trifluoroacetic acid.

The photolysis of 6-chloro-1,3-dimethyluracil in benzene afforded 1,3-dimethyl-6-phenyluracil, while the photoreaction in the presence of trifluoroacetic acid afforded 1,3-dimethylcyclooctapyrimidine-2,4-dione as a major product.
