TMSBr-Promoted Cascade Cyclization of <i>ortho</i>-Propynol Phenyl Azides for the Synthesis of 4-Bromo Quinolines and Its Applications
Difficult-to-access 4-bromo quinolines are constructed directly from easily prepared <i>ortho</i>-propynol phenyl azides using TMSBr as acid-promoter. The cascade transformation performs smoothly to generate desired products in moderate to excellent yields with good functional groups com...
