Two isomeric 4‐methyl‐6‐phenyl‐5,6,7,8‐tetrahydro‐4 H ‐1,3,2,6‐dioxathiazocine 2‐oxides were prepared, and their pmr and cmr spectra were examined. From the aromatic solvent shielding values and the magnitudes of the γ shifts, the title compounds are found to exist in the trans and cis forms in solution.
