Synthesis and characterization of indolizine and 5,6-benzo-fused indolizine derivatives with their pharmacological applications

Efficient Solvent-Free Synthesis of Indolizines Using CuBr Catalyst from Pyridine, Acetophenone, and Electron-Deficient Alkenes

“…Boruah's group synthesized indolizines by using pyridine, bromoacetophenone, and alkyne under microwave conditions [21]. The aforementioned synthesis methods have established a solid foundation for the development and application of indolizine derivatives [22][23][24][25]. However, research on indolizine is still in its early stages.…”
