Reaction Conditions:

with diethylazodicarboxylate in chloroform;toluene at 20; for 12 h;

Steps:

General procedure of the DEAD-mediated dehydrogenationof 1,2,3,4-tetrahydroquinolines

General procedure: To a 10 mL round bottom flask equipped with a magnetic stir bar, 1,2,3,4-tetrahydroquinoline (0.5 mmol), DEAD solution 40 wt% in toluene (2.2 eq, 1.1 mmol, 0.5 mL), and CHCl₃ (1.0 mL) was added. The reaction mixture was stirred at room temperature for 12 h. The mixture was concentrated on rotary evaporator. The residue was purified by column chromatography with EtOAc:hexane (1:5) to give quinolines. In case of 2f and 2m, the product spot was close to the spot of the remained DEAD. To eliminate the remained DEAD, 1 equivalent of PPh₃ was added after the reaction and the reaction mixture was stirred.^[19] After 10 min, the reaction mixture was concentrated on rotary evaporator. The residue was purified by column chromatography with CHCl₃:hexane (1:1) to give quinolines.
