The Claisen rearrangement of the ketene aminal derived by selenoxide elimination of the seleno-aminal in refluxing toluene in the presence of dihydropyran yields the expected unsaturated eight-membered lactam derivative as well as two unexpected products; the major product (resulting from a selenium re-addition reaction) was shown by X-ray crystallography to be a highly distorted transoid amide (imide) with the largest p-orbital distortion (τ = 50.6°) recorded for a cyclic amide.
