Synthesis of 6-Substituted Imidazo[2,1-b][1,3]thiazoles and 2-Substituted Imidazo[2,1-b][1,3]benzothiazoles via Pd/Cu-Mediated Sonogashira Coupling

[摘要]：The reaction of iodobenzenes with 2-amino-3-(2-propynyl)-1,3-thiazolium bromide and 2-imino-3-(2-propynyl)-1,3-benzothiazole, catalyzed by Pd/Cu, leads to the formation of 6-substituted imidazo[2,1-b][1,3]thiazoles and 2-substituted imidazo[2,1-b][1,3]benzothiazoles,respectively.
