    Description / Table of Contents: Contributions to the Chemistry of Indole, III. Deethyl-chano-ibogamine2-(2-Indolyl)cyclohexanone (3) was hydrogenated in the presence of methylamine to give the cis-methylamine 4a, which was treated with ethyl bromoacetate. The resulting ethyl aminoacetate 8a was saponified and cyclisized with PPA yielding the ketone 9, which on reduction with LiAlH4 almost quantitatively afforded the title compound 2 possessing cis-configuration between the rings C and D.
    Notes: Aus 2-[Indolyl-(2)]-cyclohexanon (3) erhält man durch hydrierende Aminierung das Methylamin 4 als cis/trans-Isomerengemisch. Das cis-Amin (4a) wird mit Bromessigester umgesetzt, der entstehende Aminosäureester 8a verseift und die Säure (8b) mittels PPA zum 8-Oxodesäthyl-chano-ibogamin (9) cyclisiert. Aus diesem erhält man mit LiAlH4 fast quantitativ die Titelverbindung 2.

    Description / Table of Contents: Contributions to the Chemistry of Indole, II Beckmann and Schmidt Rearrangements of some Indole KetonesSchmidt rearrangement of serveral indole ketones resulted in the migration of the C atom bearing the indole group to yield one amide, whereas Beckmann rearrangement led to the formation of the isomeric amide. A H-bridge between indole-NH and oxime group might be responsible for the unusual behavior of these compounds in the Beckmann rearrangement.
    Notes: Die hier untersuchten Indolyl-(2)-2′ -ketone ergeben bei der Schmidt-Reaktion selektiv ein Amid unter Wanderung des C-Atoms, das den Indolrest trägt, bei der Beckmann-Umlagerung dagegen selektiv das andere Isomere. Für das anormale Verhalten bei der Beckmann-Umlagerung kann möglicherweise eine H-Brücke, die zu spezifischer Fixierung der Oxime führt, eine Erklärung geben.
