13C NMR Spectra of Some Methyl Cyclohexanecarboxylates

13C NMR spectra of a series of stereoisomeric-substituted methyl cyclohexanecarboxylates have been obtained. The resonances for ring carbons of the isomers, in which both the methoxycarbonyl and the other groups have equatorial orientations, usually appear at a field lower than those of the isomers...

Summary:13C NMR spectra of a series of stereoisomeric-substituted methyl cyclohexanecarboxylates have been obtained. The resonances for ring carbons of the isomers, in which both the methoxycarbonyl and the other groups have equatorial orientations, usually appear at a field lower than those of the isomers in which one of the two substituents has an axial orientation. No appreciable difference in shift due to the configurational change is observed in the resonances for the substituents. Observed chemical shifts are compared with predicted values.
