Hydrogenation of dimethyl adipate over bimetallic catalysts
(Elsevier Science BvAmsterdamHolanda, 2004)
Tri-functional oligomeric polyesters prepared from new dicarboxylic acids containing several amino acids residues by Higashi methodology: synthesis, characterization, and study of solubility and thermal behavior
(Chile. Universidad Mayor, 2021)
The synthesis of polyfunctional aliphatic oligomeric polyesters (poly(ether-imido-esters;PEIEs) containing several amino acid residues is described, and their thermal properties and solubility behavior were studied. The ...
Nifedipine and nitrendipine reactivity toward singlet oxygen
(ELSEVIER SCIENCE SA, 2005-10-31)
The ability to generate singlet molecular oxygen, O-2((1)Delta(g)), and the scavenging activity of two well-known 1,4-dihydropyridines (1,4-DHPs) such as nifedipine (1,4-dihydro-2,6-dimethyl-4-(2-nitrophenyl)-3,5-pyridin ...
Synthesis and characterization of a novel series of 1,4-dihydropyridine analogues for larvicidal activity against Anopheles arabiensis
(Wiley Blackwell Publishing, Inc, 2017-09)
The new-fangled bis(4-substituted benzyl) 4-(4-substitued phenyl)-2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylate derivatives were synthesized by the union of substituted aryl aldehyde, tert-butyl acetoacetate, ammonium ...
Poly(ester)s and poly(amide)s with fluorene and diphenyl-silane units in the main chain: Effects of iodine doping on the structure and electrical conductivity
(2012)
Intramolecular charge transfer interaction between the electron donor and electro acceptor units within the polymeric structure and its optoelectronic properties were studied. The monomer, 9H-fluorene-2,7-dicarboxylic acid, ...
Labdane diterpenes from Haplopappus illinitus
(2002)
A chemical study of aerial parts of Haplopappus illinitus afforded five labdane diterpenoids whose structures were elucidated by high field NMR spectroscopy and 2D techniques. Four of them are dicarboxylic acids previously ...
Síntese, caracterização e estudo da aplicabilidade dos complexos entre ligantes carboxílicos e lantanídeos (La, Eu, Tb e Dy) como traçadores
(Universidade Federal de Minas GeraisUFMG, 2010-08-09)
A novel series of promising tracers for application in petrochemistry were rationally planned, synthesized and investigated. These new compounds are coordination compounds with some ligands such aspoli and dicarboxylic ...
