A novel library of chalcone linked thiazole-imidazopyridine (12a–j) derivatives were designed, synthesized, and their structures were characterized by 1H NMR, 13C NMR and mass spectral studies. Further, all compounds were tested for their anticancer effects on four human cancer cell lines including MCF-7 (breast carcinoma), A549 (lung carcinoma), DU-145 (prostate carcinoma) and MDA MB-231 (breast carcinoma) by employing MTT method, using etoposide as the positive control. Among them, compound 12b displayed more potent anticancer activity against four cancer cell lines when compared to the positive control.

The cyanation and formylation of imidazo[1,2-a]pyridines were developed under copper-mediated oxidative conditions using ammonium iodide and DMF as a nontoxic combined cyano-group source and DMF as a formylation reagent. Mechanistic studies indicate that the cyanation of imidazo[1,2-a]pyridines proceeds through a two-step sequence: Initial iodination and then cyanation. The cyanation has a broad substrate scope and high functional group tolerance, and can be safely conducted on a gram scale. A novel copper-mediated formylation using the widely available DMF as the formylation reagent and environmentally friendly molecular oxygen as the oxidant has also been developed. This protocol also provided a convenient approach for the synthesis of clinically used saripidem. This journal is
