    • Synthesis of new 4-nitrosophenyl-1,4-dihydropyridines of pharmacological interest 
      Santander Gutiérrez, Ingrid Paola; Núñez Vergara, Luis; Squella Serrano, Juan; Navarrete Encina, Patricio (GEORG THIEME VERLAG KG, 2003-12-18)
      The synthesis and characterization of a series of 4-nitrosophenyl-1.4-dihydropyridines derived from the respective nitro compounds of pharmacological interest is described. The complete synthetic pathway is based on the ...

      Santander Gutierrez, Ingrid Paola; Núñez Vergara, Luis; Squella Serrano, Juan; Navarrete Encina, Patricio (GEORG THIEME VERLAG KG, 2003-12-18)
      The synthesis and characterization of a series of 4-nitrosophenyl-1.4-dihydropyridines derived from the respective nitro compounds of pharmacological interest is described. The complete synthetic pathway is based on the ...
    • Synthesis of some C-3,4,5-substituted 2,6-dimethyl-1,4-dihydropyridines (4-DHPs) 
      Navarrete Encina, Patricio; Squella Serrano, Juan; Carbajo, J.; Conde, B.; Núñez Vergara, Luis (TAYLOR & FRANCIS INC, 2007)
      A series of C-3,4,5-substituted 2,6-dimethyl-1,4-dihydropyridines ( 1,4-DHPs) with pharmacological properties were prepared by a variation from the classical Hantzsch synthesis. The procedure involves treatment of the ...
    • Unexpected diastereotopic behaviour in the H-1 NMR spectrum of 1,4-dihydropyridine derivatives triggered ... 
      Da Silva, Jaqueline; Barría, Claudio; Jullian Matthaei, Carolina; Navarrete Encina, Patricio; Núñez Vergara, Luis; Squella Serrano, Juan (SOC BRASILEIRA QUIMICA, 2005-01)
      1,4-dihydropyridine derivatives constitute an important pharmacological group for the treatment of cardiovascular diseases. We have synthesised a series 4-(5'-nitro-2'-furyl)-1,4-dihydropyridine derivatives, which were ...
    • Voltammetric studies of aromatic nitro compounds: pH-dependence on decay of the nitro radical anion in mixed media 
      Carbajo, J.; Bollo Dragnic, Soledad; Núñez Vergara, Luis; Navarrete Encina, Patricio; Squella Serrano, Juan (ELSEVIER SCIENCE, 2000-12-01)
      In this report we have chosen ethyl-m-nitrobenzoate (EMNB) as a prototype of a nitroaromatic compound in order to carry out a detailed cyclic voltammetric study focused on the coupled chemical reaction of the generated ...
    • X-ray study of bilayered tilted structures in liquid crystalline side chain methacrylic polymers 
      Soto Bustamante, Eduardo; Vergara Toloza, Rafael Orlando; Saldaño Hurtado, Danilo; Navarrete Encina, Patricio (TAYLOR & FRANCIS LTD, 2003-05)
      The synthesis and measurement of thermodynamic properties of six methacrylate-based polymers were undertaken to observe the relationship between structural aliphatic features and mesophase properties. X-ray measurements ...
