Methoxy 13C chemicalshifts in methoxycyclohexanederivatives may be rationalized in terms of rotamerpopulationsabout the C–OMe bond and δ1-effects caused by steric interaction of the methoxy-group with substituents at the neighbouring 2- and 6-positions. Information on rotamerpopulations is obtained also from the 13C chemicalshifts of C-2 and C-6, and from the three-bond coupling between the proton
