readily available aryldiazonium salts, nitriles, and 2-aminoarylketones in a one-pot operation. This method relies on the in situ generation of the N-arylnitrilium intermediate from the reaction of aryldiazonium salt with nitrile, which undergoes amination/cascade cyclization/aromatization, leading to N-arylquinazolinium salts in excellent yields. Nucleophilic addition of alkoxide to these N-arylquinazolinium
从一锅操作中容易获得的芳基重氮盐,腈和2-氨基芳基酮描述了一种制备N-芳基喹唑啉鎓盐的简便方法。该方法依赖于芳基重氮盐与腈反应的原位生成N-芳基腈中间体,该胺经历胺化/级联环化/芳构化,从而以极高的收率得到N-芳基喹唑啉盐。将醇盐向这些N-芳基喹唑啉鎓盐的亲核加成提供官能化的二氢-N-芳基喹唑啉。
