Conformational analysis and absolute stereochemistry of 'spongian'-related metabolites
(Elsevier Ltd, 2004)
New degraded and rearranged diterpenoids, 5-8, have been isolated from the Antarctic sponge Dendrilla membranosa. The structure and relative stereochemistry of these compounds were determined by spectroscopic data. The ...
New aldehydes by catalytic diene cycloisomerisations
(2008)
The Rh-catalysed hydroformylation of isopropylidenecyclohexane derivatives obtained by intramolecular diene cyclisations affords the corresponding aldehydes in good yields and in a completely chemo- and regioselective ...
"Metacognición en la enseñanza y en el aprendizaje de conceptos en Química Orgánica”
(2015-08-31)
Esta investigación indaga el rol que cumple la metacognición en los procesos de enseñanza y aprendizaje de la química orgánica, se indaga al mismo tiempo, la relación que existente entre las habilidades viso-espaciales y ...
The effect of interesterification on the bioavailability of fatty acids in structured lipids
(2013)
Fatty acid (FA) profile is a critical factor in the nutritional properties of fats, but, stereochemistry may also play a fundamental role in the rate and extent to which FAs are absorbed and become available. To better ...
Madreporanone, a unique diterpene with a novel skeleton from Azorella madreporica
(2002)
A unique diterpene 1, was isolated from the altiplane Andean plant Azorella madreporica Clos (Apiaceae). The structure and stereochemistry were established by spectral methods and molecular mechanics calculations. The ...
Ligand influence on the redox properties of some copper(II) complexes with schiff bases derived from bromosalicylaldehydes and methyl or chloro-substituted anilines
(Kluwer Academic Publishers, 1986)
The synthesis, characterization and electrochemical behaviour of a new series of copper(II) complexes derivated from substituted anilines and bromosalicylaldehydes have been studied. The complexes show a square-plane ...
Molecular modeling of manganese peroxidase from the lignin-degrading fungus Ceriporiopsis subvermispora and structural comparison with other peroxidases.
(Universidad Católica de Valparaíso, 1998-08-15)
Ceriporiopsis subvermisporais a white-rot basidiomycete that produces several isoenzymes of manganese peroxidase (MnP). A cADN of one of them (MnP13-1) has been isolated and sequenced. The deduced aminoacid sequence ...
Synthesis, structure, and reactivity of (n5:n1-C5Me4(CH2)2NMe2) Re(CO)2. Electron transfer behavior of a nitrosyl derivative
(Elsevier, 2014)
The UV irradiation of a hexane solution of the complex (n5-C5Me4(CH2)2NMe2)Re(CO)3 (1) afforded the
chelated species (n5:n1-C5Me4(CH2)2NMe2)Re(CO)2 (2). The molecular structure of 2 has been determined
by X-ray ...
Photochemical C-Cl bond activation of trichloroarenes by the rhenium complex (eta(5)-C5Me5)Re(CO)(3). X-ray structure of trans-(eta(5)-C5Me5)Re(CO)(2)(2-methoxy-4,5-dichlorophenyl)chloride
(ELSEVIER SCIENCE, 2003-12-15)
Photochemical reaction of (eta(5)-C5Me5)Re(CO)(3), with 2,4,5-trichloroanisole and 3,4,5-trichlorotrifluoromethylbenzene yields (eta(5)- C5Me5)Re(CO)(2)(C6H2Cl2(MeO))Cl (1) and (eta(5)-C5Me5)Re(CO)(2)(C6H2Cl2(CF3))Cl, (2) ...
Intermolecular C-Cl activation reaction of (pi(5)-C5R5)Re(CO)(3) (R = H, Me) with pentachlorobenzene: X-ray structure of cis- and trans-(eta(5)-C5Me5)Re(CO)(2)(2,3,4,5-C6HCl4)Cl and its conversion to (eta(6)-C5Me4CH2)Re(CO)(2)(2,3,4,5-C6HCl4)
(American Chemical Society, 2006-06-26)
Photochemical reaction of (eta(5)-C5R5)Re(CO)3 (R = H, Me) with pentachlorobenzene (lambda = 350 nm, hexane solution) yields trans-(eta(5)-C5R5)Re(CO)(2)(2,3,4,5-C6HCl4) (trans-1, R = Me; 2, R = H) formed by insertion of ...
