    Description / Table of Contents: Rudbeckiolide, a Dimeric Sesquiterpene Lactone from Rudbeckia laciniataRoots of Rudbeckia laciniata afforded in addition to known compounds minute amounts of an unusual dimeric sesquiterpene lactone (9). Its constitution was elucidated by detailed 1H NMR spectroscopy, and the stereochemistry followed from the couplings observed and especially from the results of NOE difference spectroscopy.
    Notes: Wurzeln von Rudbeckia laciniata ergeben neben bekannten Verbindungen in sehr kleiner Menge ein ungewöhnliches dimeres Sesquiterpenlacton (9). Dessen Konstitution konnte durch eingehende 1H-NMR-spektroskopische Untersuchungen, die Stereochemie aus den beobachteten Kopplungen sowie vor allem durch die Ergebnisse der NOE-Differenzspektroskopie geklärt werden.
