A study of the double bond reactivity in Δ3-cyclohexene derivatives with one polar substituent in the side chain and Me substituents in the ring has shown that the preferred conformation for these compounds, indepenent of their stereochemistry, has the polar group axial, giving rise to supra-annular interaction. Such interaction decreases the nucleophilicity of the ring double bond. A similar study
在Δ的双键的反应性的研究3个与该环中的侧链和Me的取代基一个极性取代基环己烯衍生物已经表明,对于这些化合物的优选构象,它们的立体化学的indepenent,具有极性基团的轴向,从而产生环上相互作用。这种相互作用降低了环双键的亲核性。Δ的类似研究4 -octalin -1,2-二羧酸和它们的酯已经表明,在对比的是报道构象分配3个的优选构象,即使对于反式衍生物是那些在diaxial位置的极性subtituents。
