    Description / Table of Contents: Synthese von Alkaloiden des Reserpin-Typs, III. - Synthese von rac-deserpidin und einem rac-Raunescin-EpimerAusgehend von der in der vorausgehenden Mitteilung beschriebenen, zur Darstellung von Yohimbanen mit normalem Molekülgerüst verwendeten Schlüssel-Synthesevorstufe 2, wurden rac-Deserpidin (1b) und das rac-Raunescin-Epimer 9c mit epi-allo- bzw. allo-Gerüst hergestellt. Im Laufe der Synthese wurden einige Stereoisomere des in Position 18 substituierten allo-Yohimbins hergestellt und auf spektroskopischem und chemischem Wege charakterisiert.
    Notes: Starting from the key intermediate 2 previously used for the preparation of derivatives with a normal yohimbane skeleton, the synthesis of rac-deserpidine (1b) and the rac-raunescine epimer 9c, having an epi-allo and allo skeleton, respectively, has been performed. In the course of the synthesis several stereoisomers of C-18-substituted allo-yohimbine have been prepared and characterized by spectroscopic and chemical means.
