A copper(I) catalyzed cascade reaction of 2-haloaryl isothiocyanates with isocyanides for the construction of benzo[d]imidazo[5,1-b]thiazoles has been demonstrated. Good to excellent yields could be achieved. This [3+2] cycloaddition and C–S coupling reaction represents an extremely simple way to construct benzo[d]imidazo[5,1-b]thiazoles.
已经证明了铜(I)催化2-卤代芳基异硫氰酸酯与异氰酸酯的反应,可用于构建苯并[ d ]咪唑并[5,1- b ]噻唑。可以实现良好的优良收率。这种[3 + 2]环加成反应和CS偶联反应是构建苯并[ d ]咪唑并[5,1- b ]噻唑的一种极其简单的方法。
