Abstract Norbornane‐ or norbornene‐fused 2‐aryldihydro‐1,3‐oxazines, ‐1,3‐oxazin‐2‐ones and – 1,3‐oxazine‐2‐thiones were synthesized and studied by 1 H and 13 C NMR spectroscopy to reveal the spectral effects of the saturation of the skeleton, diexo or diendo ring annellation and isomerism in compounds containing the oxygen and nitrogen hetero atoms in isomeric positions.
