A three-component Povarov reaction of aldehydes, anilines, and benzyl N-vinylcarbamate in the presence of 0.1 equiv of a chiral phosphoric acid afforded cis-2,4-disubstituted tetrahydroquinolines in good yields and excellent enantiomeric excesses. This three-component reaction enables a very short synthesis of torcetrapib.
