报道了一种布朗斯特酸/可见光氧化还原接力催化合成喹唑啉(硫)酮的方法. 在温和的反应条件下, 原料2-氨基苯乙酮和异(硫)氰酸酯先后经历了布朗斯特酸催化的[4+2]环化反应和光催化的碳-碳键断裂反应, 得到各种不同取代的喹唑啉-2,4-二酮和喹唑啉-2-硫酮-4-酮. 该合成方法具有能源和溶剂绿色、无金属催化剂、起始原料简单以及以空气作为绿色氧化剂等特点.

A relay Brønsted acid/visible-light photoredox catalysis strategy for the synthesis of quinazolin(thi)ones is developed. In this procedure, 2-aminoacetophenones and iso(thio)cyanates undergo Brønsted acid catalyzed [4+2] annulation, followed by photocatalyzed C—C bond cleavage reaction. A wide range of diversely substituted quinazoline-2,4-diones and quinazoline-2-thione-4-ones were synthesized under mild conditions. The protocol features eco-benign energy source and solvent, metal-free catalysts, simple starting materials and air as green oxidant.

Key words: relay catalysis, visible-light catalysis, green synthesis, quinazolinone
