    Description / Table of Contents: Zusammenfassung Die aus den methoxysubstituierten 3-Vinylindolen1 und2 zugänglichen Cycloaddukte3,5 und7 lassen sich mitDDQ zu den coplanar-anellierten Carbazolen4,6 und8 dehydrieren. Verbindung4a, die auch durch eine Röntǵenstrukturanalyse charakterisiert wurde, zeigt signifikante Cytotoxizität gegen Humantumor-Zellinien (K562 und RXF93).
    Notes: Summary The cycloadducts3,5, and7, readily available from methoxy-substituted 3-vinylindoles1 and2, were dehydrogenated withDDQ to the coplanar [a]-anellated carbazoles4,6, and8. Compound4a, also characterized by X-ray structural analysis, shows significant cytotoxicity against K562 und RXF393 human tumor cell lines.

    Notes: The applicability of 2D EXSY NMR spectroscopy for studying quantitatively the dynamic behaviour in three aroylcyanoketene-S, S-dimethylacetals was tested by means of 1H NMR spectroscopy. It can be concluded that the method is a reasonable qualitative supplement to complete line-shape analysis.
