- An efficient access to 2,3-diarylimidazo[1,2-a]pyridines via silver(I)-catalyzed C-H bond functionalization
-
Abstract: An efficient and economic Ag-catalyzed method for the direct cross-coupling of unactivated imidazo[1,2-a]pyridines with arylboronic acids has been developed. This approach leads to the formation of corresponding 2,3-diarylimidazo[1,2-a]pyridine derivatives as biological and pharmaceutical materials of interest in good yields under mild reaction conditions.

- Synthesis of Disubstituted 3-Phenylimidazo[1,2-a]pyridines via a 2-Aminopyridine/CBrCl3 α-Bromination Shuttle
-
A versatile protocol for the synthesis of disubstituted 3-phenylimidazo[1,2-a]pyridines by coupling 2-aminopyridine with phenylacetophenones, phenylacetones, or β-tetralone has been developed. Isolated yields of up to 97% were obtained at 80 °C within 5 h

- Efficient access to 2,3-diarylimidazo[1,2-a ]pyridines via a one-pot, ligand-free, palladium-catalyzed three-component reaction under microwave irradiation
-
An expeditious one-pot, ligand-free, Pd(OAc)2-catalyzed, three-component reaction for the synthesis of 2,3-diarylimidazo[1,2-a]pyridines was developed under microwave irradiation. With the high availability of commercial reagents and great efficiency in expanding molecule diversity, this methodology is superior to the existing procedures for the synthesis of 2,3-diarylimidazo[1,2-a]pyridines analogues.

- Synthesis and biological evaluation of 2,3-diarylimidazo[1,2-a]pyridines as antileishmanial agents
-
A novel series of 2,3-diarylimidazo[1,2-a]pyridines was synthesized and evaluated for their antileishmanial activities. Four derivatives exhibited good activity against the promastigote and intracellular amastigote stages of Leishmania major, coupled with a low cytotoxicity against the HeLa human cell line. The impact of compound lipophilicity on antiparasitic activities was investigated by Log D comparison. Although LmCK1 could be the parasitic target for three compounds (13, 18, 21), the inhibition of another target is under study to explain the antileishmanial effect of the most promising compounds.
