Abstract

The13C-nmr spectra of a group of diisophorone carboxylic acids have been determined and fully assigned. The spectral data confirm, in some cases decisively, the formulation of members of this series of compounds. In the light of the spectral information, the stereochemistry of the C(4)-C(5)-region of the diisophorone ring-system is discussed, with special reference to the configuration of the 4-substituents.

Zusammenfassung

Die13C-Kernresonanzspektren einer Anzahl von Diisophoron-carbonsäuren wurden aufgenommen und die Signale den Atomen des Kohlenstoffgerüstes zugeordnet. Die so erhaltenen Beziehungen ermöglichen ihrerseits die Bestätigung — und in gewissen Fällen die entscheidende Sicherung — der Struktur weiterer Beispiele dieser Verbindungsreihe. Die sterische Anordnung des C(4)-C(5)-Bereiches im Diisophoron-Ring-System, insbesondere die Konfiguration von 4-Substituenten, wird an Hand der spektroskopischen Ergebnisse erörtert.
