Synthesis of 5 -2-Phenyl-l,2,3,4-tetrahydroquinoline

2-Phenylquinoline (20.0 mg 0.097 mmol), BINOL-phosphate 1 (1.4 mg, 2 mol %), Hantzsch dihydropyridine (59.2 mg, 0.234 mmol) and benzene (2.0 mL) were added to a screw-capped vial and the mixture was exposed to an argon atmosphere. The resulting yellow solution was allowed to stir at 60 °C for 12 h. The solvent was evaporated in vacuo, and the residue was purified by column chromatography over silica gel to afford the amine as yellow oil (92 %, 97 % ee). 

HPLC conditions -hexane/2-propanol = 95/5, flow rate = 0.6 mL min, major enantiomer 18.98 min minor enantiomer tR = 25.43min.
