The synthesis of a new family of methoxy‐substituted [2.7]‐ and [2.8]paracyclophanes linked by 3‐oxapentamethylene‐1,5‐dioxy and hexamethylene‐1,6‐dioxy bridges has been carried out by using the McMurry methodology. Related indole compounds were also synthesised. Olefin‐to‐diol ratios depended on the bridge length, the structure of the aromatic ring and the reaction conditions. Macrocyclisation, the
通过使用McMurry方法,合成了由3-氧杂戊基亚甲基-1,5-二氧基和六亚甲基-1,6-二氧基桥连接的新的甲氧基取代的[2.7]-和[2.8]对环环烷家族。还合成了相关的吲哚化合物。烯烃与二醇的比例取决于桥的长度,芳环的结构和反应条件。如通过NMR光谱法和根据理论计算所观察到的,大环化,甲氧基取代基和刚性吲哚部分的存在限制了构象平衡。合成的化合物显示微摩尔微管蛋白聚合抑制活性。与康布雷他汀,密切相关的斯蒂芬类相比,对大环化产生的微管蛋白聚合抑制活性的构象影响
