Biomimetic flavin-catalyzed aldehyde oxidation.
The oxidation of alkyl and aryl aldehydes to their corresponding carboxylic acids has been achieved through the action of a biomimetic bridged flavin catalyst. The reaction uses readily available 35% aqueous hydrogen peroxide and is operationally simple. The oxidation is a green and sustainable reaction, obviating chlorinated solvents with minimal byproducts.
متن کاملEfficient and highly aldehyde selective Wacker oxidation.
A method for efficient and aldehyde-selective Wacker oxidation of aryl-substituted olefins using PdCl(2)(MeCN)(2), 1,4-benzoquinone, and t-BuOH in air is described. Up to a 96% yield of aldehyde can be obtained, and up to 99% selectivity can be achieved with styrene-related substrates.
متن کاملDrosophila melanogaster alcohol dehydrogenase: mechanism of aldehyde oxidation and dismutation.
Drosophila alcohol dehydrogenase (Adh) catalyses the oxidation of both alcohols and aldehydes. In the latter case, the oxidation is followed by a reduction of the aldehyde, i.e. a dismutation reaction. At high pH, dismutation is accompanied by a small release of NADH, which is not observed at neutral pH. Previously it has been emphasized that kinetic coefficients obtained by measuring the incre...
متن کاملEnzymatic oxidation of vitamin A aldehyde to vitamin A acid.
Studies indicating that vitamin A (1) and vitamin A aldehyde (2) are metabolized to water-soluble degradation products and CO% provide support for the suggestion (3) that there exists an oxidative pathway of major importance in the metabolism of vitamin A. The detection of vitamin A aldehyde in the liver (4, 5) and observations (6-8) that dietary vitamin A acid supports the growth of vitamin A-...
متن کاملAerobic oxidation of NHC-catalysed aldehyde esterifications with alcohols: benzoin, not the Breslow intermediate, undergoes oxidation.
Benzoin (and neither the Breslow intermediate nor the NHC-aldehyde tetrahedral adduct) has been unambiguously identified as the oxidised species in aerobic NHC-catalysed aldehyde esterifications.
