Abstract

The configurations and conformations of cis‐ and trans‐N‐methyl‐ and ‐N‐benzyl‐4,5‐ and ‐5,6‐tetramethylenetetrahydro‐1,3‐oxazines were determined by 1H and 13C NMR spectroscopy. The cis isomers are conformationally homogeneous, having the hetero atom attached to the cyclohexyl ring, in the axial and equatorial positions, respectively, in the 5,6‐ and 4,5‐tetramethylene compounds, similar to the case of the 2‐p‐nitrophenyl‐substituted analogues investigated previously.
