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

The con6gurations and conformations of cis-and tram-N-methyl-and -N-benzyl-4,5-and -5,6tetramethylenetetrahydm-l,3-o~es were determined by 'H and -C NMR spectroscopy. The cis isomers are conformationally homogeneous, having the hetero atom attached to the cydohexyl ring, in the axial and equatorial
## Abstract The ^1^H NMR spectra of isomeric 5,6βdimethylβ2βoxoβ1,4βdioxans have been recorded and the pertinent chemical shifts and coupling constants determined. The parameters indicate that both isomers exist as an equilibrium mixture of interconverting half chair ring conformations.
