Regioselective synthesis and molecular docking studies of functionalized imidazo [1,2-a]pyridine derivatives through MCRs

초록

A efficient protocol has been developed for the synthesis of regioselective imidazo[1,2-a]pyridine and imidazo[1,2-a]pyrimidine derivatives through cascade reaction between 2-aminopyridine, arylelglyoxal, and 4-hydroxypyran via three-component reaction to prepare targeted compounds with good to excellent yields. The advantages of this transformation are a catalyst-free reaction, green solvent, operationally simple, scalable, and eco-friendly. The product collects with simple filtration which avoided tedious and expensive purification techniques. In addition, computational studies like molecular docking were conducted to provide the theoretical possibilities of binding these types of synthesized compounds to the VEGFR2 receptors as potential key inhibitors of tumor cell growth and angiogenesis. © 2023, The Author(s), under exclusive licence to Springer Nature Switzerland AG.
