Description

Ban Van Phuc leads a ten-author team reporting a one-pot route to complex fused ring compounds, in a chemistry paper published in two thousand twenty-five. The products, long-named pyrido-imidazo-quinolines, belong to families prized in medicinal chemistry. Building them usually takes several steps.

Their method starts from brominated imidazopyridines, ammonia, and the solvent DMSO, open to air. A copper iodide and proline catalyst first couples carbon to nitrogen. Air oxidation then closes the final ring in the same pot. Yields were high across a series of derivatives. The same trick produced sulfur-containing cousins in good yields. Fewer steps and cheap catalysts make the route attractive for library synthesis in drug discovery.
