Characterization by NMR of Ozonized Methyl Linoleate
No presente estudo o linoleato de metila ozonizado com índice de peróxidos de 1.800 mmol-equiv. kg foi caracterizado quimicamente. Os efeitos do ozônio sobre o linoleato de metila produz hidroperóxidos, ozonideos e aldeídos, os quais foram identificados por técnicas de ressonância magnética nuclear de H e C, monoe bidimensional. O linoleato de metila padrão e o linoleato de metila ozonizado mos...
متن کاملAsymmetric Hydrogenation and Transfer Hydrogenation of Ketones
Optically active alcohols are important building blocks in the synthesis of fine chemicals, pharmaceuticals, agrochemicals, flavors and fragrances as well as functional materials (Arai & Ohkuma, 2011; Klingler, 2007). Furthermore, molecular hydrogen is without doubt the cleanest reducing agent, with complete atom efficiency. Therefore, the catalytic, asymmetric hydrogenation (AH) of prochiral k...
متن کاملHomogeneous catalytic hydrogenation of amides to amines.
Hydrogenation of amides in the presence of [Ru(acac)3] (acacH=2,4-pentanedione), triphos [1,1,1-tris- (diphenylphosphinomethyl)ethane] and methanesulfonic acid (MSA) produces secondary and tertiary amines with selectivities as high as 93% provided that there is at least one aromatic ring on N. The system is also active for the synthesis of primary amines. In an attempt to probe the role of MSA ...
متن کاملAsymmetric homogeneous hydrogenation of 2,5-disubstituted furans.
A homogeneous catalyst system for the asymmetric cis-hydrogenation of 2,5-disubstituted furans leading to 2',3'-dideoxynucleoside analogues is described. Best enantioselectivities (ee values of up to 72%) were obtained with cationic rhodium complexes ligated by diphospholanes of the butiphane family. The selectivity of the hydrogenation was reversed by the addition of a base or a polar protic s...
متن کاملMetabolism of monoepoxides of methyl linoleate: bioactivation and detoxification.
Leukotoxin (ltx) and isoleukotoxin (iltx) methyl esters, are metabolites of methyl linoleic acid, an essential fatty acid. They have been associated with acute respiratory distress syndrome. The observed toxicity of ltx and iltx is, in fact, due to the metabolism of the epoxides to their corresponding diols by soluble epoxide hydrolase (sEH). Herein, we demonstrate that ltx/iltx are toxic in a ...
