Methoxy 13C chemical shifts in methoxycyclohexane derivatives may be rationalized in terms of rotamer populations about 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 rotamer populations is obtained also from the 13C chemical shifts of C-2 and C-6, and from the three-bond coupling between the proton at C-1 and the methoxy-carbon atom.
