Phenyliodine(III) diacetate-induced oxidation of 2-(2-hydroxynaphthyl)benzoxazoles in alcohols, regioselectively afforded dearomatized products: 1-(benzoxazol-2-yl)-1-alkoxynaphthalen-2(1H)-ones and 1-(benzoxazol-2-yl)naphthalene-2,3-diones. Further, these products were also synthesized one-pot either from (E)-1-(((2-hydroxyphenyl) imino)methyl)naphthalen-2-ol or 2-aminophenol 2-hydroxynaphthal...
The pyrrolidine-2,5-dione ring in the title compound, C(15)H(15)NO(6), is in a twisted conformation with the acetyl C atoms projecting to opposite sides of the ring. The acetyl groups lie to opposite sides of the five-membered ring. The benzene ring is roughly perpendicular to the heterocyclic ring, forming a dihedral angle of 76.57 (14)° with it. In the crystal, mol-ecules are connected throug...
The xanthophyll carotenoids lutein (L), zeaxanthin (Z) and meso-zeaxanthin (MZ) are found at the macula, the central part of the retina, where they are referred to as macular pigment (MP). MP is studied in human subjects because of its proven role in enhancing visual function and its putative role in protecting against age-related macular degeneration. These benefits are probably due to the ant...
The antifungal effect of sodium diacetate on inhibiting the growth of some bread spoiling molds was examined both in culture media and in flat bread “In situ”. In the first step, the antifungal effect of different concentrations of sodium diacetate: 0, 1000, 2000, 3000, 4000, and 5000 ppm were examined against Aspergillus sp., Aspergillus niger, Rhizopus sp., and Penicillium sp. The results ind...
