A new application of flavin derivatives in visible light photocatalysis was found. 1-Butyl-7,8-dimethoxy-3-methylalloxazine, when irradiated by visible light, was shown to allow an efficient cyclobutane ring formation via an intramolecular [2+2] cycloaddition of both styrene dienes, considered as electron-rich substrates, and electron-poor bis(arylenones), presumably proceeding via an energy transfer mechanism.
Photoinduced Electron Transfer (PET) cyclization and photooxygenation of 2,6-diaryl-1,6-heptadienes and 2,7-diaryl-1,7-octadienes

The 2,6-diaryl-substituted 1,6-heptadienes 3a-c and the 2,7-diaryl-substituted 1,7-octadienes 4a-b were cleanly converted into the corresponding anellated cyclobutanes 5 and 6, resp., when irradiated under photoelectron-transfer conditions (9,10-dicyanoanthracene in acetonitrile). Only for 4c did the rearranged compound 7c become the dominant photoproduct. Oxygen trapping experiments with formation of endoperoxides 8, 9 were successful in the case of the electron-rich substrates 3b, c and 4c. VCH Verlagsgesellschaft mbH, 1996.

Mechanism-based design, two-step synthesis, and in vitro antimalarial testing showed thermally stable, crystalline, bicyclic endoperoxides 2a and 2b to be potent antimalarials. Their reduction by FeBr2 proceeds via oxy-radicals and then carbon
A "frustrated" cope rearrangement: Thermal interconversion of 2,6-diphenylhepta-1,6-diene and 1,5-diphenylbicyclo[3.2.0]heptane

The title reaction constitutes a reliable model of a nonconcerted, diradical mechanism closely related to a Cope rearrangement. Its activation parameters relate to a transition state approximated by 1,5-diphenylcyclohepta-1,5-diyl (7). Force field calcula
