Abstract:

A simple and effective synthesis of spinochrome D (1) (2,3,5,6,8-pentahydroxy-1,4-naphthoquinone), a pigment of different sea urchin species, has been developed starting from 2,3-dichloro-5,8-dihydroxy-1,4-naphthoquinone (13), easily available by cycloacylation of 1,4-dimethoxybenzene (11) with dichloromaleic anhydride (12). Bromination of 13 with either bromine or dioxane dibromide to 6-bromo-2,3-dichloro-5,8-dihydroxy-1,4-naphthoquinone (21), followed by nucleophilic substitution of the halogen atoms by methoxy groups in 21 and hydrolysis of trimethyl ether 10 produce the target compound in

A short and efficient synthesis of balsaminone A, a dinaphthofuran-1,4-dione, is described. The eight-step synthesis features two alternate pathways including a base-induced coupling reaction of 4-methoxy-1-naphthol and 2,3-dichloro-1,4-naphthoquinone, as well as a light-mediated cyclization of 1,1'-binaphthoquinone to afford the dinaphthofurandione core. Subsequent ortho formylation yielded a known precursor to balsaminone A, affording the natural product in 20–27% yield. This represents a moderate increase from the previous synthesis of 7.4% yield.

Abstract:

Abstract This study was conducted to evaluate the influence of chloride ions (Cl−) on organic contaminants decolorization by the Fe0-activated persulfate process (PS/Fe0), as well as the generation of transformation products. Orange II (OII) was chosen as the target pollution. The results indicated that Cl− influenced the OII decolorization by PS/Fe0 system, resulting in the generation of chlorine-containing by-products. OII containing Cl− solution can be efficiently decolorized by PS/Fe0 process, and the decolorization efficiencies changed depending on Cl− concentration due to the reaction be
