(Chemical Equation Presented) Active ingredient: Optically active tetrahydroquinolines and tetrahydroisoquinolines can be obtained by the asymmetric hydrogenation of quinolines and isoquinolines with chloroformates as the activating reagent (e.g., ClCO2Bn, see scheme). The method has been applied to the asymmetric synthesis of several naturally occurring alkaloids. Bn = benzyl.

The stereoselectivity in the addition of the enantiomerically pure (2-bromophenyl)acetaldehyde acetals 3a-g to the acylimines 4a,b is investigated. Based on this reaction a novel asymmetric synthesis for the 1-phenyl-tetrahydroisoquinoline 8 is elaborated.
