Macrocyclic hosts are prepared in 80–90% yields by using intramolecular hydrogen-bonding interactions to direct the cyclisation; in the absence of such effects, intermolecular hydrogen-bonding interactions template the formation of catenanes.
利用分子内氢键相互作用来引导环化,可以制备出产率高达 80%-90% 的大环宿主;如果没有这种效应,分子间氢键相互作用则是形成卡烯烃的模板。
