4-triazole-3,5-dione (PTAD) was subjected to a triplet-sensitized di-π-methane rearrangement. Hydrolysis of the resulting urazol 18 gave the hydrocarbon 7. Hydrolysis of 18 at lower base concentrations led to isomeric stable semicarbazides 24 and 25, which were submitted NiO2 or MnO2 oxidation, to give the target compound 7, and oxidation products 26 and 27.
在[4 + 2]环加成17的2,3-二亚甲基-1,2,3,4-四氢-1,4- methanonaphthalene和4-苯基-4- ħ -1,2,4-三唑-3,5-对二酮(PTAD)进行三重态敏化的二-π-甲烷重排。所得的urazol 18的水解得到烃7。在较低的碱浓度下水解18会导致异构的稳定的氨基脲24和25,它们被NiO 2或MnO 2氧化,得到目标化合物7,以及氧化产物26和27。
