A concise and versatile route to functionalised naphthazarins via 1,3,4,5,6,8-hexamethoxynaphthalene is described and is illustrated with the synthesis of three natural products, aureoquinone, boryquinone and 3-ethyl-2,7-dihydroxynaphthazarin.

Some substituted monohydroxylated naphthazarins (5,8-dihydroxy-l,4-naphthoquinones) were synthesized and studied by IR-spectroscopy in aprotic organic solvents at ambient temperature. Two narrow stretching mode bands in the high frequency range 3540-3410
Chemistry of naphthazarin derivatives 7. Determination of structures of substituted 2,6(7)-dihydroxynaphthazarins by UV and IR spectroscopy

, p. 88 - 94 (2001)
A set of substituted 2,6- and 2,7-dihydroxynaphthazarins were synthesized. The difference in the UV spectra of alkaline alcoholic solutions of 2,6- and 2,7-dihydroxynaphthazarins allows the reliable differentiation of the structures of these compounds. Th
Concise formal total synthesis of hybocarpone and related naturally occurring naphthazarins

, p. 992 - 1001 (2007/10/03)
A concise formal total synthesis of the cytotoxic bisnaphthazarin derivative hybocarpone has been completed through the development of routes to the synthetic precursor, 3-ethyl-2-hydroxy-5,7,8-trimethoxy-6-methyl-1,4- naphthoquinone. The oxidation of 3-e
