✦ Synopsis

The conformational energies of the title compounds were extrapolated from solution lg F NMB measurements to vapour phase dielectric medium. Vapour phase values were satisfactorily reproduced by MM2 computations including electrostatic interactions between charges obtained by the PEOE method.

The configuration and conformation of some diastereomeric 4-hydroxy-cis-and -h.uns-l-oxadecalins were inferred by 'H and '3C NMR spectroscopy. The results obtained indicate that the cis-fused compounds are conformationally homogeneous, having the oxygen atom attached to the cyclohexyl ring in the ax
