A facile method for the rapid synthesis of benzoacridines has been described. This protocol promoted by p-toluenesulfonic acid starts from aromatic aldehydes and N-phenyl naphthylamines, affording a variety of benzoacridines in 30–90 % yields under metal-free conditions. The present approach involves a cascade of condensation, Friedel-Crafts alkylation, annulation and dehydroaromatization in one pot
描述了一种快速合成苯并吖啶的简便方法。该方案由对甲苯磺酸促进,从芳香醛和N-苯基萘胺开始,在无金属条件下以 30-90% 的收率提供各种苯并吖啶。本方法涉及在一个锅中进行级联的缩合、Friedel-Crafts 烷基化、环化和脱氢芳构化。
