Photochemical Synthesis of Polycyclic Pyrimidines through the Acid Catalyzed Cycloaddition of 6-Chloro-1-methyluracil to Methyl Substituted Benzenes
UV-irradiation of 6-chloro-l-methyluracil with benzene in the presence of TFA resulted in 1,2-cycloaddition and susequent elimination of HCl gave a cyclooctapyrimidine-2,4-dione. Similar acidExpand

TLDR
It was elucidated that the photolysis of the esters affords the geminate radical pair 28, which in turn recombines to cyclohexadienone intermediates 29 and 30, which accelerates not only the nucleophilic attack of alcohol to 29 and30 but also other processes. Expand
New photochemical rearrangements and extrusion reactions of aromatic compounds induced by an intramolecular [2+2] photocycloaddition between a naphthalene and a resorcinol moiety
Abstract An intramolecular [2+2] photocycloaddition between a naphthalene and a resorcinyl moiety was followed by an acid catalyzed rearrangement leading to tricyclic tetrahydrofuran derivatives. TheExpand
Acid-catalyzed photoreaction of 6-chloro-1,3-dimethyluracil and mesitylene: formation of photocycloadducts and their characterization.
TLDR
In contrast to the previously reported short time required (1 h) for photolysis of 6-chloro-1,3-dimethyluracil and mesitylene, in the presence of TFA, prolonged irradiation of this same mixture yields novel pentalenopyrimidine derivatives, including diazapentacyclo. Expand
