A complete and unambiguous assignment of H and C nuclear magnetic resonance (NMR) signals of 29 naphthoquinones is reported on the basis of oneand two-dimensional NMR techniques (H, C, H-H correlated spectroscopy (COSY) and H-C heteronuclear multiple-bond correlation (HMBC)). This is the first report distinguishing data between para-naphthoquinones, orthoand para-furanonaphthoquinones isomers.
