Swern-type oxidation of various 7-halogenobicyclo[4.1.0]heptane-2,3- or -3,4-diols affords the corresponding bicyclic diketones which undergo in situ ring expansion and loss of hydrogen halide to give α-tropolones in high yield. The quantitative conversion of the isolable 1,4-diketone 26 into the γ-tropolone acetate 27 has been achieved.
各种7-卤代双环[4.1.0]庚烷2,3-或-3,4-二醇的Swern型氧化可提供相应的双环二酮,该二环二酮在原位发生环扩环并损失卤化氢,从而在高浓度下得到α-对苯二酚屈服。已经实现了将可分离的1,4-二酮26定量转化为乙酸γ-托酚酮27。
