The configurations of the Diels-Alder adducts of maleic anhydride with 2,3-dimethylnaphthalene and 6,6-diphenylfulvene have been investigated by NMR spectroscopy. Restricted rotation and non-planar conformations about the N–N bond in the corresponding <I>N</I>-aminoimide derivatives of the adducts have been employed in solving the structural problem. While the <I>N</I>′,<I>N</I>′-diacetyl system has been shown to be a suitable probe for configurational assignment, <I>N</I>′-acetyl-<I>N</I>′-aroyl-<I>N</I>′-aminoirnide derivatives have been found to be a more diagnostic probe even to simple adducts.
