Tf2O-mediated Mild Synthesis of 6H-Chromeno[4,3-b]quinolines
A facile and versatile synthesis of 6 H -chromeno[4,3-b ]quinolines has been achieved through triflic anhydride/2-fluoropyridine (Tf 2 O/2-F-Pyr)-promoting domino intramolecular cycloaddition reactions of salicylic-acid-derived N -phenyl- ortho -propynyloxy benzamides under mild, and metal-free conditions. This protocol is efficient, scalable, and well compatible with a broad scope of substrates bearing halogens, trifluoromethyl
