    Description / Table of Contents: Indoles and Indole Alkaloids, XVII. Influence of the Configurations of Alkyl Substituents in Positions 2 and 4a on the Chiroptical Properties of Tetrahydro-4a-carbazolesThe absolute configurations of the 2,4a-dialkyltetrahydro-4a H-carbazoles 1-6 were assigned by means of the CD curves of the optically active reference compounds 7-10. The configurations of the substituents in the positions 2 and 4a exert a quite different influence on the signs of the CD curves of the compounds of typ I-III depending on the nature of the chromophoric systems. The spatial requirement of the substituent in position 2 plays also an important role in this respect.
    Notes: Mit Hilfe der CD-Kurven der optisch aktiven Vergleichssubstanzen 7-10 konnten die absoluten Konfigurationen der 2,4a-Dialkyltetrahydro-4aH-carbazole 1-6 aufgeklärt warden. Bei diesen Verbindungen vom Typ I-III üben die Konfigurationen der Substituenten in den Positionen 2 and 4a in Abhängigkeit von der Art des chromophoren Systems einen ganz unterschiedlichen Einfluß auf die Vorzeichen der CD-Kurven aus. Auch die Raumerfüllung des Substituenten in Position 2 spielt dabei eine wesentliche Rolle.
