Configuration of the Praziquantel Enantiomers

The levorotatory (methanol) enantiomer of the anthelminthic agent praziquantel (rac-1) is R-, the dextrorotatory S-configurated.This assignment is based upon CD-spectra of both enantiomers and additionally confirmed by conversion of (+)- and (-)-2 to the pyrazinoisoquinolines 3 of known configuration.
