Synthesis and characterization of tungstophosphoric acid-modified mesoporous sponge-like TUD-1 materials
(Springer, 2018-07)
Mesoporous sponge-like siliceous materials (TUD-1) were synthesized using TEOS (tetraethylorthosilicate) as a precursor of silica and TEA (triethanolamine) as a mesostructure-directing agent. Different TEOS/TEA molar ratios ...
Síntese e estudo físico-químico de 1,3-imidazóis 2,4,5-trissubstituídos derivados de benzocalcogenazóis
(Universidade Federal de Santa MariaBrasilQuímicaUFSMPrograma de Pós-Graduação em QuímicaCentro de Ciências Naturais e Exatas, 2016-07-29)
In the following work, an unprecedented series of 2,4,5-trisubstituted 1,3-imidazoles were synthesized from 1,2-diketones and aryl aldehydes, targeting the union of two classes of heterocyclic rings, the imidazoles and ...

Synthesis, antileishmanial activity and cytotoxicity of 2,3-diaryl- and 2,3,8-trisubstituted imidazo[1,2-a]pyrazines
(Elsevier, 2015)
A series of original 2-phenyl-3-(pyridin-4-yl)imidazo[1,2-a]pyrazines and the 3-iodo precursors, bearing a polar moiety at the C-8 position, was synthesized and evaluated for their antileishmanial activities. Two derivatives ...
Estudio computacional de reacciones pseudo multicomponente para la síntesis de imidazoles trisustituidos
(Universidad de los AndesQuímicaFacultad de CienciasDepartamento de Química, 2019)
Los imidazoles trisustituidos presentan un gran potencial como agente biológico donde se resalta su papel como anticancerígeno debido a la inhibición de procesos relacionados con topoisomerasas y adicionalmente como ...
Síntese de 1,3-imidazois-2,4,5-trissubstituídos derivados de calcogenofenos
(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 2014-08-24)
In the following work, a series of new 2,4,5 trisubstituted 1,3-imidazoles 11 and 12 were synthesized from 1-aryl-2-(chalcogenophen-2-yl)-1,2-diketones targeting the union of two classes of interesting heterocycles the ...
