The proton NMR spectra of epimeric mixtures of menthone ( 1 ), carvomenthone ( 2 ), carquejone ( 3 ), 2,5‐dimethyl‐1,4‐cyclohexanedione ( 4 ) and piqueridione ( 5 ) were studied using the chemical shift reagent Eu(DPM) 3 . The results allow quantifications of the epimers and some conformational assignments to be made.
