Mn(III)-Catalyzed aerobic oxidation including complex rearrangements.

What is it about?

Synthesis of 1,2-dioxan-3-ols using Mn(III)-catalyzed aerobic oxidation is important for organic synthesis. But, the reaction of methylenebis(cyclohexane-1,3-dione) enols gives unusual 6a-hydroxy-2,3,4,6a,7,8,9,10aoctahydro-1H-benzo[c]chromene-1,6,10-triones. To understand the mechanism is interesting for organic chemistry.
