Navarrete Encina, Patricio; Salazar, Ricardo; Vega-Retter, Christian; Pérez, Karina; Squella Serrano, Juan; Núñez Vergara, Luis (Sociedade Brasileira de Química, 2010)Substituted chromenos, dihydropyridines and pyridines have been important in the syntheses of compounds having interesting pharmacological properties. Therefore, we found of interest to synthesize chromenopyridines and ...

Soto Bustamante, Eduardo; Saldaño Hurtado, Danilo; Vergara Toloza, Rafael Orlando; Navarrete Encina, Patricio; Athanassopoulou, M. A. (TAYLOR & FRANCIS LTD, 2003-01)The phase characterization of two homologous series of liquid crystalline methacrylic monomers based on omega-hexyl- and omega-butyloxysalicylaldimine groups, with different alkoxy tails, is presented. The liquid crystalline ...
