      Pérez Cruz, Karina Angélica (Universidad de Chile, 2010)
      La presente memoria da cuenta de la síntesis, caracterización física y electroquímica de cuatro nuevos compuestos: 1-etoxicarbonil-2,4-dimetil-5-oxo-5H-cromeno[3,4- c]dihidropiridina; 1-etoxicarbonil-2,4-dimetil-5-oxo- ...
    • Synthesis and antioxidant study of new polyphenolic hybrid-coumarins 

      Pérez Cruz, Karina Angélica; Moncada-Basualto, Mauricio; Morales Valenzuela, Javier; Barriga González, Germán; Navarrete Encina, Patricio; Núñez Vergara, Luis; Squella Serrano, Juan; Olea Azar, Claudio (Elsevier, 2018-05)
      The antioxidant capacity of hydroxylated coumarins and hydroxybenzoic acids has been widely described. However, there is little information on the antioxidant activity when both systems are functionalized. In this work, ...
    • Synthesis and electrochemical oxidation of hybrid compounds: Dihydropyridine-fused coumarins 

      Pardo Jiménez, Viviana Gladys; Barrientos, C.; Pérez Cruz, Karina Angélica; Navarrete Encina, Patricio; Olea Azar, Claudio; Núñez Vergara, Luis; Squella Serrano, Juan (2014)
      In this paper, a series of six dihydropyridine-fused coumarins were synthesized and electrochemically characterized in dimethylformamide (DMF). Dihydropyridine ring oxidation on glassy carbon electrode (GCE) for condensed ...
