dc.description.abstractFor a new steroidal lactol, jaborosalactol 24, isolated from Jaborosa parviflora, NMR spectroscopy residual dipolar couplings and powder X-ray diffraction analysis independently gave the same stereochemistry at C23-C26. Conventional NMR spectroscopic techniques, such as NOE and 3J coupling-constant analysis failed to unambiguously determine this stereochemistry.
dc.description.abstractEine Frage der Technik: Dieselbe Konfiguration an C23–C26 wurde für das neue Steroidlactol Jaborosalactol 24 (1), isoliert aus Jaborosa parviflora, auf zwei unabhängigen Wegen bestimmt: NMR-spektroskopisch aus dipolaren Restkupplungen und durch Röntgenpulverbeugung. Herkömmliche NMR-spektroskopische Techniken wie die Analyse von NOEs und 3J-Kopplungskonstanten lieferten keine eindeutigen Ergebnisse.
