Photooxygenation of furans in water and ionic liquid solutions

Photooxygenation of differently functionalized furans is investigated in aqueous solutions and in ionic liquids [emim]Br and [bmim]BF4. The reaction is generally selective and the final products derive from rearrangement of the intermediate endoperoxides, depending mainly on the polarity and/or nucleophilic nature of the solvent.

Photosensitized Oxidation of Furans; XI. A Simple General Method for the Synthesis of 3-, 4-, or 3,4-Functionalized 5-Hydroxyfuran-2(5H)-ones (4-Hydroxy-2-butenolides)

The title compounds 3 are prepared, in good yields, by methylene blue photosensitized oxidation of furans 1 in acetone and thermal conversion of the solutions of the intermediate endo-2,5-peroxides 2.
