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.

Naphthofuroquinones are of great value in medicinal chemistry. In this letter, a facile method for highly regioselective synthesis of both linear and angular naphthofuroquinones has been developed via iodine mediated cyclization of 2-hydroxy-3-substitutedvinyl-1,4-naphthoquinones under very mild conditions.
