Treatment of 1,3-dienes with the pyridinium dichromate (PDC)-t-BuOOH reagent system leads directly to the formation of 4-tert-butyldioxy-2-enones in good yield under mild reaction conditions.

We report a highly efficient and selective catalytic system, ABNO (9-azabicyclo-[3.3.1]nonane N-oxyl)/HNO3, for the aerobic oxidation of substituted furans to cis-2-ene-1,4-diones under mild reaction conditions using oxygen as the oxidant. The catalyst system is amenable to various substituted (mon-, di-, and tri-) furans and tolerates diverse functional groups, including cyano, nitro, naphthyl, ketone, ester, heterocycle, and even formyl groups. Based on the control and 18O-labeling experiments, the possible mechanism of the oxidation is proposed.

We have developed an efficient metal-free route for the synthesis of 1,4-enedione derivatives under microwave irradiation by reacting easily available arylmethylketones with DMSO or diphenyl sulfoxide in the presence of TBAI and persulfate. The reaction is very clean and completes within very short time. All the reagents and catalysts are cheap and environmentally benign. In addition, the E-isomer of the products can easily be transformed into the Z-isomer by using eosin Y photocatalyst under the irradiation of white CFL.
