	Title	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.

	Title	Notiz zur Absolutkonfiguration des Epoxipiperolids Note on the Absulute Configuration of Epoxipiperolide
	Abstract	The epoxide-ring of (+)-5-[£rans-(Z)-2,3-epoxy-l-methoxy-propylidene]-4-methoxy-2(5H)-furanone (1) was opened hydrogenolyti-cally (palladium/charcoal) to (+)-(2S)-5-(2-hydroxy -1 -methoxy -3 -phenylpropylidene) -4 -methoxy-2(5H)-furanone (2) whose absolute configuration (2S) was determined applying Horeau's method. For the natural product (+)-l itself follows (2 S,3 Reconfiguration.

	Title	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.

	Title	Zur Stereochemie von Silybin
	Abstract	The X-ray Structure of Silybin from Silybum marianum G aertn. was determined. The com pound was found to be a diastereom eric m ixture (1 : 1) in the benzodioxane part of the molecule explaining several tentative aspects about the structure known from NM R-m easurem ents and HPLC-separations.
