In this study, a series of fused-heterocyclic derivatives were systematically designed and synthesized using an efficient route, and evaluated in terms of GLP-1R agonist activity. We employed short synthetic steps and reactions that are tolerant of the presence of various functional groups and suitable for parallel operations to enable the rapid generation of libraries of diverse and structurally complex small molecules. Of the compounds synthesized, 3-(8-chloro-6-(trifluoromethyl)imidazo[1,2-a] pyridin-2-yl)phenyl methanesulfonate (8e) was the most potent agonist with an EC50 of 7.89 μM, and thus is the compound with the greatest potential for application. These findings represent a valuable starting point for the design and discovery of small-molecule GLP-1R agonists that can be administered orally.
Sequential Regioselective Diorganochalcogenations of Imidazo[1,2-<i>a</i>]pyrimidines Using I<sub>2</sub>/H<sub>3</sub>PO<sub>4</sub> in Dimethylsulfoxide
The dichalcogenation of imidazoheterocycles led to the first functionalization of imidazo[1,2-a]pyrimidine cores on the C6-position. The methodology, involving iodine/dimethylsulfoxide oxidation of diaryldichalcogenides, started with C3-chalcogenation, followed by C6 selanylation, activated in acidic medium. This novel sequential dichalcogenation strategy proceeded efficiently with excellent regioselectivity
