Yield: 69%
Reaction Conditions:
with thiourea S,S-dioxide;diethyl 2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylate in chloroform at 60; for 24 h;
Steps:
2.3 General Procedure for Transfer Hydrogenationof 2-Substituted Quinolines
General procedure: An oven-dried flask was fitted with magnetic stirring barand charged with 2-substituted quinoline (0.10 mmol),thiourea dioxide (1 mol%), Hantzsch dihydropyridine(2.5 equiv.) and chloroform (1 mL). The resulting mixturewas stirred at 60 °C for 24-48 h. The solvent wasremoved under reduced pressure and the residue was purifiedby column chromatography on silica gel using hexane/EtOAc (20:1) as eluent to yield the corresponding1,2,3,4-tetrahydroquinolines.
