The intramolecular Friedel-Crafts cyclisation of ω-arylalkanoic acids, which is in the benzene series a valuable synthetic route to bicyclic ketones with medium-sized and large rings, has been investigated with ω-(1-naphthyl)alkanoyl chlorides. The lower members, including naphthyl-caproic acid, close the ring at position 2 to form IV. The higher homologous acids show a preference for annellation at
ω-芳基链烷酸的分子内Friedel-Crafts环化是苯系列中具有中型和大环的双环酮的有价值的合成途径,已用ω-(1-萘基)链烷酰氯进行了研究。包括萘基-己酸的低级成员在位置2处闭合环以形成IV。较高的同源酸显示优先选择7位的壬基化,从而提供了一种新型的异核萘环酮(VII)。在ω-(1-萘基)癸酸环化过程中,1,4环的闭合与1,7类型竞争。
