Four isomeric 4,7‐dimethyl‐6‐phenyl‐5,6,7,8‐tetrahydro‐4 H ‐1,3,6‐dioxazocin‐2‐ones and four isomeric 4,7‐dimethyl‐6‐phenyl‐5,6,7,8‐tetrahydro‐4 H ‐1,3,2,6‐dioxathiazocine 2‐oxides were prepared. On the basis of the nmr chemical shifts due to the γ‐effect, the stereochemical structures are discussed.
