Abstract:

The buffered permanganate oxidation of (-)-myternal, a member of the pinene family, provides the α-hydroxyketone (-)-(1R,3S,5R)-3-hydroxy-6,6-dimethylbicyclo[3.1.1]heptan-2-one in preparative yield (65% on a multigram scale). This α-hydroxyketone is oxidized, in a second reaction, to the α,β-diketone (1R,5R)-6,6-dimethylbicyclo[3.1.1]heptane-2,3-dione ("PinDione"). As both oxidations are fast, simple, safe, inexpensive, good-yielding, and multigram scalable, these transformations are a preparative expansion of the pinane family.
