strategy used to obtain the quinonederivatives was initially based on the Diels–Alder cycloaddition between myrcene and several p-benzoquinone derivatives, followed by cyclisation of the prenyl side chain in the case of anthracene-1,4-diones. The most promising compounds, displaying MIC values in the low μg/mL range, were those bearing one or two chlorine atoms attached to the quinone ring. Time-kill curves

A series of new furoterpenyl-1,4-naphtho(anthra)quinones have been prepared via oxidative cyclization of the corresponding 2-hydroxy-3-butenyl-1,4-naphtho(anthra)quinones. Depending on the reaction conditions the 1,2-quinones or the 1,4-quinones were obtained. Several new furo-1,4-anthraquinones were also obtained by condensation of 2,3-dichloroquinones with 1,3-dicarbonyls. The compounds synthesized have been evaluated for their cytotoxicity against neoplastic cell lines, some of them being effective below the micromolar level. (c) 2006 Elsevier Ltd.

A new procedure to obtain anthracene-1,4-diones from p-benzoquinones and myrcene, in the presence of acids, is described. The cycloaddition reaction between α-myrcene and p-benzoquinones, followed by oxidation, led to 1,4-naphthoquinones or 1,4-anthraquinones depending upon whether the Lewis acid used in the Diels-Alder reaction, was present or absent during oxidation; furthermore, traces of acid in
