The examination of strongly biased systems by integration of the NMR signals is difficult, since the peak(s) of the minor conformer must be both detected and positively identified. In the case of 5f and 5e, no signal corresponding to the axial conformer could be detected in pyridine. In these cases the reported value is an estimation of the lower limit of the equilibrium constant. The small signal of the methine proton of the axial conformer of 5h (at 5.79 ppm) was identified by a NOESY spectrum which displayed a magnetization transfer cross peak between this signal and the methine proton of the major (axial) conformer at 7.35 ppm.

2O obtained from pyridine also showed the molecule in the bis-equatorial conformation. The structure could not be sufficiently refined, however.
