Triethylamine catalyzed rearrangement of the substituted bicyclic cycloheptatriene endoperoxides 9, 10,12, 13, 20, 21, 22 and 30 underwent different reaction modes and resulted in the formation of ring contraction products in the case of 9, 10, 12 and 13. However, 20, 21, and 30 provided rearranged diketones 23, 24 and 32 almost in quantitative yield. The mechanism of these reactions was discussed
三乙胺催化的取代双环环庚三烯内过氧化物9、10、12、13、20、21、22和30的重排经历不同的反应模式,并在9、10、12和13的情况下导致形成环收缩产物。然而,20,21,和30提供重新排列二酮23,24和32几乎以定量产率。讨论了这些反应的机理。
