An efficient and practical method for the synthesis of medicinally important acridines from readily available o-aminoaryl ketones and arylboronic acids was developed using copper(II)-mediated relay reactions that involve intermolecular Chan–Lam cross-coupling and subsequent intramolecular Friedel–Crafts-type reactions. A sole promoter, i.e., Cu(OTf)2, was used; therefore, strongly acidic and basic
利用铜(II)介导的中继反应,涉及分子间Chan-Lam分子间交叉偶联和随后的分子内Friedel-Crafts型合成,开发了一种有效,实用的方法,该方法可从容易获得的邻氨基苯甲酮和芳基硼酸合成具有医学意义的cr啶。反应。使用唯一的促进剂,即Cu(OTf)2;因此,不需要强酸性和碱性条件,难以获得或昂贵的底物,添加剂和贵金属催化剂。
