afforded bicyclo[6.3.0]undecatriene derivatives instead of tricyclic compounds, the latter of which are well known as a basic skeleton of naturally occurring octanoids. On the basis of two experiments with deuterated substrates, a plausible reaction mechanism for the construction of these products was proposed.
在回流的甲苯中用[RhCl(CO)2 ] 2处理十二碳三烯炔衍生物,实现了环异构化,生成了三环[6.4.0.0 2,6 ]十二碳二烯。然而,一碳短的十一碳三烯炔衍生物可以提供双环[6.3.0]十一碳三烯衍生物,而不是三环化合物,后者是众所周知的天然辛烷类化合物的基本骨架。基于氘化底物的两个实验,提出了构建这些产物的合理反应机理。
