The Avarol-Avarone Redox Behaviour in Acetonitrile [PDF]

open access: yesCroatica Chemica Acta, 1985
The oxidation of avarol and the reduction of avarone were studied at a Pt electrode in acetonitrile-tetraethyl-ammonium perchlorate media. The oxidation of avarol in acetonitrile takes place by formation of a two electron oxidation product, presumably the »protonated avarone«. The reduction of avarone takes place in two steps by formation of the stable

Total Synthesis of Dactyloquinone A and Spiroetherone A via a Metal-Hydride Hydrogen Atom Transfer (MHAT) Process and a Quinol-Enedione Rearrangement. [PDF]

open access: yesAngew Chem Int Ed Engl
Total syntheses of the meroterpenoid quinones dactyloquinone A and spiroetherone A were achieved from a common intermediate through the following original key steps: a metal‐hydride hydrogen atom transfer (MHAT) process with a quinone monoacetal in the case of dactyloquinone A, and a quinol–enedione rearrangement in the case of spiroetherone A ...
