A class of substituted 1,2,3-benzotriazines are obtained in tandem mode reaction by means of Cu-catalyzed intramolecular C-H activation of aniline, isocyanides and dialkyl azadicarboxylate in acetonitrile at room temperature in good yields. The speed and ease of carrying out this three-component reaction under mild one-pot conditions with available materials, without using column chromatography, make
在室温下,通过乙苯中铜催化苯胺,异氰酸酯和氮杂二羧酸二烷基酯的铜催化分子内CH活化,以串联模式反应获得一类取代的1,2,3-苯并三嗪。在温和的一锅条件下,利用可获得的材料进行这种三组分反应的速度和简便性,而无需使用柱色谱法,使其成为合成取代的1,2,3-苯并三嗪衍生物的一种选择方法。
