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
−烯家族成员(-)-myternal的缓冲高锰酸盐氧化可提供α-羟基酮(-)-(1 R,3 S,5 R)-3-羟基-6,6-二甲基双环[3.1。 1]庚烷-2-酮的制备产率(以克计为65%)。在第二反应中,该α-羟基酮被氧化为α,β-二酮(1 R,5 R)-6,6-二甲基双环[3.1.1]庚烷-2,3-二酮(“ PinDione”)。由于两种氧化反应都快速,简单,安全,廉价,收率好,可扩展至多克级,因此这些转变是family烷系列的制备性扩展。
