| CD-Spectroscopic Investigations for the Determination of the Absolute Configuration of (4/?,6S,7S)-Serricomin  | | | Abstract
| The absolute configuration of the conformationally flexible (4i?,6S,7S)-serricornin, a non natural isomer of the female-produced sex pheromone of the cigarette beetle (Lasioderma serricorne), was determined by comparison of measured and calculated circular dichroism spectra. The rotational strengths were calculated by means of the semiempirical CNDO/2S-method. The total synthesis was accomplished by the SAMP/RAMP-hydrazone method. | | |

| CD-Spectroscopic Investigations for the Determination of the Absolute Configuration of a-Alkylated 1,4-CycIohexanedione Derivatives  | | | Abstract
| The absolute configuration of the conformationally flexible six membered ring system 2-me-thyl-and 2,6-dimethyl-l,4-cyclohexanedione monoethylene acetal was determined by compar ison of measured and calculated CD spectra. The rotational strengths were calculated by means of the CNDO/S-method assuming R at the stereogenic center. The results were compared with the predictions made by the octant rule. The enantiomerically pure material was synthesized via the corresponding SAMP-and RAMP-hydrazones. | | |
