    Description / Table of Contents: Reactions with Indole Derivatives, XIX. Stereoselective Cyclisations in the Indole SeriesSubstituted 1-allylnorharman derivatives rearrange after reaction with formaldehyde via a char-ge-induced sigmatropic process and subsequently cyclise stereoselectively to yield substituted indoloquinolizidines. The constitution and configuration of the reaction products is described.
    Notes: Substituierte 1 -Allylnorharmanderivate unterliegen nach Umsetzung mit Formaldehyd einer raschen ladungsinduzierten sigmatropen Umlagerung und cyclisieren anschließend stereo-selektiv zu substituierten Indolochinolizidinen. Die Konstitution und die Konfiguration der Reaktionsprodukte wird beschrieben.
