Abstract An efficient and convenient one-pot cascade synthesis of 2,4-dichloroquinazolines directly from isatin-3-oximes with the addition of bis(trichloromethyl)carbonate and triarylphosphine oxide was developed, leading to substituted quinazolines in moderate to excellent yields. The efficiency of this transformation was demonstrated by compatibility with a range of functional groups. Thus, the method represents a convenient and practical strategy for the synthesis of substituted 2,4-dichloroquinazolines. Graphical Abstract

由双（三氯甲基）碳酸酯和三芳基氧化膦介导的靛红-3-肟一锅级联环扩大为 2,4-二氯喹唑啉

摘要 开发了一种直接从靛红-3-肟与双（三氯甲基）碳酸酯和三芳基膦氧化物直接高效、方便地一锅级联合成 2,4-二氯喹唑啉的方法，以中等至优异的收率获得取代的喹唑啉。与一系列官能团的兼容性证明了这种转化的效率。因此，该方法代表了合成取代的 2,4-二氯喹唑啉的一种方便实用的策略。图形概要
