In this paper, the [3 + 2] cycloaddition reaction of thiobenzoyl group derivatives with sulfoxonium ylide was studied, which can directly synthesize 2,4-diarylthiazoles with different structures. Compared with the traditional reaction of producing thiazole, using palladium catalysts is able to make the reaction milder and lower in cost. Thus, a group of 2,4-diarylthiazoles can be easily synthesized
本文研究了硫代苯甲酰基衍生物与硫鎓叶立德的[3+2]环加成反应,可直接合成不同结构的2,4-二芳基噻唑。与传统生产噻唑的反应相比,使用钯催化剂可以使反应更温和,成本更低。因此,以这种方式可以容易地以中等至高产率合成一组2,4-二芳基噻唑。
