Terpenoids. XXXVIII.1 Interconversion of Eremophilone, Hydroxyeremophilone and Hydroxydihydroeremophilone. The Relative Stereochemistry of Eremophilone and its Reduction Products2,3
The structures of hydroxyeremophilone and its various derivatives have been verified using NMR spectroscopy. All four of the thermodynamically stable C-8 and C-9 eremophilanones have now been prepared and their opticalrotatorydispersioncurves and NMR spectra compared. Three of these ketones have been prepared from the naturally occurring hydroxyeremophilone by variation of the experimental conditions
