applied as an effective catalyst in the dehydrative cyclization and subsequent rearrangement of unsaturated tertiary alcohols. This is the first report on catalyzing such a reaction with a Brønsted acid. Scope and limitations of this cyclopentene‐forming reaction sequence are presented. Furthermore, substrate‐selective conversion as well as competitive inhibition are described and provide evidence
布朗斯台德酸性间苯二酚[4]芳烃六聚体可作为一种有效的催化剂用于脱水环化和不饱和叔醇的后续重排。这是关于用布朗斯台德酸催化这种反应的第一份报告。介绍了这种形成环戊烯的反应顺序的范围和局限性。此外,还描述了底物选择性转化以及竞争性抑制作用,这些证据提供了反应在自组装结构腔内进行的证据。此外,还报道了封装的乙酸环丙酯的形成环丁酮的分子内氢化物转移。
