    • 8,8-Diethyl-1,4,5,8-tetrahydronaphthalene-1,4,5-trione 
      Vega, Andrés; Ramírez Rodríguez, Oney; Martínez Cifuentes, Maximiliano; Ibáñez, Andrés; Araya Maturana, Ramiro (WILEY-BLACKWELL PUBLISHING, INC, 2009-02)
      The title molecule, C14H14O3, contains two fused six-membered carbon rings with keto groups at positions 1, 4 and 5 and a gem-diethyl group at position 8. The molecule is close to planar (maximum deviation = 0.044 angstrom), ...
    • 9,10-dihydroxy-4,4-dimethyl-5,8-dihydroanthracen-1(4H)-one 
      Ramírez Rodríguez, Oney; Martínez Cifuentes, Maximiliano; Ibáñez, A.; Vega, Andrés; Araya Maturana, Ramiro (BLACKWELL PUBLISHING, 2008-07)
      In the title molecule, C16H16O3, the ring system is planar and an intramolecular hydrogen bond is present. The molecular packing is dominated by an intermolecular hydrogen bond and by pi-stacking interactions [interplanar ...
    • Electrochemical characterization of hydroquinone derivatives with different substituents in acetonitrile 
      Salazar, Ricardo; Vidal, Jorge; Martínez Cifuentes, Maximiliano; Araya Maturana, Ramiro; Ramírez Rodríguez, Oney (Royal Soc Chemistry, 2015)
      The effect of carbonyl groups in the ortho position with respect to a hydroxyl group on the electrochemical oxidation of hydroquinones in acetonitrile is studied. The electrochemical response of hydroquinone on a glassy ...
    • Electrospray ionization mass spectrometric fragmentation of hydroquinone derivatives 
      Almodovar, Iriux; Ramírez Rodríguez, Oney; Barriga, Andrés; Caroli Rezende, Marcos; Araya Maturana, Ramiro (Wiley, 2011)
      The fragmentation patterns of nine di-, tri- and tetracyclic hydroquinones with potential antitumor activity were rationalized by invoking competing mechanisms that included sterically accelerated homolytic cleavage, ...
    • Electrospray ionization mass spectrometric fragmentation of hydroquinone derivatives - ERRATUM 
      Almodovar, Iriux; Ramírez Rodríguez, Oney; Barriga, Andrés; Caroli Rezende, Marcos; Araya Maturana, Ramiro (Wiley, 2011)
    • Phytochemical screening and antioxidant activity of seven native species growing in the forests of southern ... 
      Armas-Ricard, Merly de; Quinán Cárdenas, Francisco; Sanhueza, Harold; Pérez Vidal, Rodrigo; Mayorga Lobos, Cristina Alejandra; Ramírez Rodríguez, Oney (MDPI, 2021)
      The genus Nothofagus is one of the most abundant in the subantarctic Patagonian forests. Five species inhabit these ecosystems, three evergreen (Nothofagus betuloides, Nothofagus dombeyi, and Nothofagus nitida) and two ...
