    • Complete assignment of the H-1 and C-13 NMR spectra of 2-phenyl-3H-naphtho[2,1-b][1,4]oxazin-3-one, ... 
      Márquez, Amelia; Saitz Barría, Claudio; Cañete Molina, Alvaro Félix; Rodríguez Bustos, Héctor; Jullian Matthaei, Carolina (JOHN WILEY & SONS LTD, 1998-06)
      The H-1 and C-13 NMR spectra of 2-phenyl-3H-naphtho[2,1-b][1,4]oxazin-3-one, 2-p-methoxyphenylnaphtho[1,2-d]oxazole and 2-phenylnaphtho[1,2-d]oxazole were totally assigned using a combination of one-and two-dimensional NMR ...
    • Polarographic and spectrophotometric behavior of some N-para-phenyl substituted benzamidines 
      Squella Serrano, Juan; Núñez Vergara, Luis; Rodríguez Bustos, Héctor; Márquez, Amelia; Rodríguez Mellado, J. M.; Blazquez, M.; Roldán, E.; Domínguez, M. (INST ORGANIC CHEM AND BIOCHEM, ACAD SCI CZECH REPUBLIC, 1991-12)
      Five N-p-phenyl substituted benzamidines were studied by DC and DP polarography in a wide pH range. Coulometric results show that the overall processes are four-electron reductions. Logarithmic analysis of the waves indicate ...
    • Reacción entre el dipolo-1,3 enmascarado de una oxazolinona y 1-nitroso-2-naftol. Una nueva síntesis de ... 
      Saitz Barría, Claudio; Cañete Molina, Alvaro Félix; Márquez, Amelia; Muñoz, Lucía; Rodríguez Bustos, Héctor (Sociedad Chilena de Química, 1996)
      El azometin-ilido de la 2-p-metoxifenil-4-fenil-2-oxazolin-5-ona reacciona por ciclo adición 1,3-dipolar con ambos tautómeros del 1-nitroso-2-naftol. La reacción forma dos naftoxazoles: 2-fenilnafto[1,2-d]oxazol,2-p-met ...
