    Description / Table of Contents: Zusammenfassung Konformationsanalysen von einigen 3-Vinyl-1H-indolen, ausgehend von Röntgenstrukturgeometrien, wurden mit den Methoden der Quantenchemie und Kraftfeldmechanik durchgeführt. Die aus quantenchemischen Rechnungen erhaltenen Ladungen, Grenzorbitale und molekularen elektrostatischen Potentiale stellen verläßliche Reaktivitätsindices zur Vorhersage der Ergebnissse vonDiels-Alder-Reaktionen mit 3-Vinyl-1H-indolen dar.
    Notes: Summary On the basis of X-ray geometries, a theoretical conformational study of some 3-vinyl-1H-indoles was performed with quantum chemistry and molecular mechanics programs. Charge, frontier orbitals, and the molecular electrostatic potential derived from quantum chemistry calculations of 3-vinyl-1H-indoles are reliable reactivity parameters to predict the outcome of theDiels-Alder reaction.

    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.

    Reaktionen von 2,3-Dichlormaleinimiden mit methylenaktiven Verbindungen (1979)

    Notes: Reactions of 2,3-Dichloromaleimides with Methyleneactive Compounds2,3-Dichloromaleimides 1 react with activated methylene compounds mainly under monosubstitution to give 2-6. Replacement of the second chloroatom gives 2,3-disubstituted maleimides 9-15 and stable ylides 16-27 with pyridine and triphenylphosphine, respectively. A general synthesis for such maleimid-ylides was found in a one-batch reaction from 2,3-dichloromaleimides 1 with methyleneactive compounds and pyridine or triphenylphosphine.
