Combes Quinoline Synthesis PDF

An intramolecular proton transfer is followed by an E2 mechanism , which causes a molecule of water to leave. Deprotonation at the nitrogen atom generates a Schiff base , which tautomerizes to form an enamine that gets protonated via the acid catalyst, which is commonly concentrated sulfuric acid H2SO4. The second major step, which is also the rate-determining step , is the annulation of the molecule. Immediately following the annulation , there is a proton transfer, which eliminates the positive formal charge on the nitrogen atom.
