Oxidation reactions have been extensively studied in the context of the transformations of biomass=derived furans. However, in contrast to the vast literature on utilizing the stoichiometric oxidants, such as m=CPBA and NBS, catalytic methods for the oxidative furan=recyclizations remain scarcely investigated. Given this, we report a means of manganese=catalyzed oxidations of furan with low loading, achieving the Achmatowicz rearrangement in the presence of hydrogen peroxide as an environmentally benign oxidant under mild conditions with wide functional group compatibility.

Phthalide annulation of 2-alkylpyridin-3-ones results in the formation of the unexpected 2-aza-1-cyano-4-hydroxy-anthraquinones, the cyano moiety originating from the 3-cyanophthalide. These compounds hold great potential against Epstein-Barr Virus Early
