Enantiomericallypure hexahydroquinolinones of the structural type 9 were prepared by a variation of the Hantzsch synthesis in which an optically active acetoacetate served as a chiral auxiliary reagent. Determinations of the de and ee values are described. The absoluteconfigurations of the optically pure products were characterized by single-crystal X-ray analysis. The antipodes 9a and 9b exhibited
