(Universidad de Chile, 2007)En la presente memoria se reporta la caracterización electroquímica y la reactividad con radicales libres, alquilo y alquilperoxilo ABAP-derivados de tres nuevas 1,4 dihidropiridinas C4-substituidas (3,4,5-trihidroxifenil-DHP, ...
-
(2011)Chromenopyridines constitute a structurally diverse class of compounds with a wide range of bioactivities and increasing presence in drugs. Here we analyze the scope of the synthetic methodology to access this nucleus with ...
-
(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 ...
-
(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 ...
