The title compounds (S)-(+)-8 and (R)-(-)-8 have been prepared by an asymmetric synthesis that is based on stereoselective additions to the chiral N-acylisoquinoliniumion 3. The absolute configuration of these compounds has been determined by an X-ray analysis performed on the intermediate 5. According to the results of this study the stereochemical assignment for (S)-(+)-8 and (R)-(-)-8 described in the literature has to be revised.
