Acharya, Swadhin Swaraj;Bhaumick, Prabhas;Kumar, Rohit;Choudhury, Lokman H. research published 《 Iodine-Catalyzed Multicomponent Synthesis of Highly Fluorescent Pyrimidine-Linked Imidazopyridines》, the research content is summarized as follows. Herein, we report a metal-free one-pot three-component reaction of aryl Me ketones, 2-aminopyridines, and barbituric acids for the synthesis of pyrimidine-linked imidazopyridines using a catalytic amount of mol. iodine in DMSO medium. This process involves a one-pot C-H oxidation, followed by the formation of one C-C and two C-N bonds. A wide variety of aryl Me ketones and 2-aminopyridines were found to be suitable for this methodol. The UV and fluorescence properties of the synthesized products were studied in water and DMSO media. Most of the synthesized products exhibited very good to excellent fluorescence quantum yield. Among all the products, compounds 4p (I) and 4q (II) showed the maximum fluorescence quantum yield (0.36) in water medium under basic conditions and compound 4c (III) showed the maximum fluorescence quantum yield (0.75) in DMSO medium.
