    Description / Table of Contents: Reactions with Indole Derivatives, XXXI Stereoselective Total Syntheses of GeissoschizineStereoselective techniques of the construction of the sp2- as well as the sp3-hybridized centers of geissoschizine (1) are reported. The exocyclic E-configurated double bond may principally be installed by an elimination process, higher stereoselectivity is gained by an α-methylene lactame rearrangement.
    Notes: Es werden stereoselektive Techniken zum gezielten Aufbau der sp2 - und der sp3-hybridisierten Zentren des Geissoschizins (1) angegeben. Die exocyclische E-konfigurierte Doppelbindung kann prinzipiell über einen Eliminierungsprozeß, mit ausgeprägter Stereoselektivität jedoch über eine α-Methylen-Lactam-Umlagerung eingeführt werden.
