A series of amides (III-XI and XVII) and esters (XII-XV) of the Diels-Alder adducts, anthracene-crotonic acid (I), anthracene-fumaric acid (II) and β-naphthol-fumaric acid (XVI) have been prepared and their PMR spectra recorded.The PMR data indicate that N,N-dimethylamide and N-methylanilide derivatives of the adducts have restricted rotation about the N-CO and C-CO bonds.A trans-stereochemistry have been assigned to H-11 and H-12 in compounds I-XV and to H-2 and H-3 in compound XVI.
