Synthese von Heterocyclen mit Hydroxymethylenketonen. XIV [1]. Zur Regioselektivit�t der Reaktion von Acetylacetaldehyd mit Tryptamin
摘要:
The range of substitution products of tryptamine with acetoacetaldehyde as substituent at the basic or the indole nitrogen (2, 3) is completed by a product containing the substituent in the indole alpha-position (5). It is formed by ring opening of the tetrahydro-beta-carboline 4. The reaction conditions are commented and the H-1-NMR spectra comparatively discussed. The synthesis of the azocino-indole 7 is described.
