interactions. Altogether 22 constitutional isomers of hexahydroazulene should exist; three new isomers (1k, 1ℓ, and 1m) are presented here, ten were described earlier, but the reinvestigation of the dehydration route of bicyclic alcohol 11 showed that one of the ten structures has to be revised.
(Ž)-Cyclodec -1-烯-6-炔(3)生成三个共轭hexahydroazulenes 3 → 1K → 1C,1ℓ cyclodecyne的FVP条件下,而闪光真空热解(FVP)(2)导致1,2,9 -癸三烯(9)。我们将2(开环)和3(开环)的不同热行为归因于不同的跨环相互作用。总共应存在六氢氮杂的22种结构异构体;三种新的异构体(1k,1ℓ和1m),这里已经介绍过,前面已经描述了十个,但是对双环醇11的脱水途径的重新研究表明,十个结构之一必须进行修改。
