A biocatalytic method for the chemoselective aerobic oxidation of aldehydes to carboxylic acids

Herein, we present a study on the oxidation of aldehydes to carboxylic acids using three recombinant aldehyde dehydrogenases (ALDHs). The ALDHs were used in purified form with a nicotinamide oxidase (NOx), which recycles the catalytic NAD+ at the expense of dioxygen (air at atmospheric pressure). The reaction was studied also with lyophilised whole cell as well as resting cell biocatalysts for more convenient practical application. The optimised biocatalytic oxidation runs in phosphate buffer at pH 8.5 and at 40 C. From a set of sixty-one aliphatic, aryl-Aliphatic, benzylic, hetero-Aromatic and bicyclic aldehydes, fifty were converted with elevated yield (up to >99%). The exceptions were a few ortho-substituted benzaldehydes, bicyclic heteroaromatic aldehydes and 2-phenylpropanal. In all cases, the expected carboxylic acid was shown to be the only product (>99% chemoselectivity). Other oxidisable functionalities within the same molecule (e.g. hydroxyl, alkene, and heteroaromatic nitrogen or sulphur atoms) remained untouched. The reaction was scaled for the oxidation of 5-(hydroxymethyl)furfural (2 g), a bio-based starting material, to afford 5-(hydroxymethyl)furoic acid in 61% isolated yield. The new biocatalytic method avoids the use of toxic or unsafe oxidants, strong acids or bases, or undesired solvents. It shows applicability across a wide range of substrates, and retains perfect chemoselectivity. Alternative oxidisable groups were not converted, and other classical side-reactions (e.g. halogenation of unsaturated functionalities, Dakin-Type oxidation) did not occur. In comparison to other established enzymatic methods such as the use of oxidases (where the concomitant oxidation of alcohols and aldehydes is common), ALDHs offer greatly improved selectivity.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 22913-24-2, help many people in the next few years.Recommanded Product: Methyl benzo[b]thiophene-2-carboxylate

Synthesis of novel 2-aminoimidazo[4,5-b]pyridines, including the thieno analogue of the cooked-food mutagen IFP

Eight new compounds, including three new ring systems obtained via the Friedlunder condensation of ortto-aminothiophenecarbaldehydes 11, 21 and 24 with creatinine (8), are reported. The condensation afforded 1, which is the thieno analogue of the cooked-food mutagen IFP (2-amino-1,6-dimethylfuro[2,3-e] imidazo[4,5-b]pyridine), and the benzothieno[2,3-e]- and benzothieno[3,2-e] imidazo[4,5-b]pyridines 2 and 3. Attempts to condense 11 with isocreatinine (12) were unsuccesful. Desulfurization of 3 gave the known cooked-food carcinogen PhIP, The 2-nitro (4) and 2-hydroxy (5) derivatives of 3 are reported. The related 2-amino-1-methyl-imidazo[4,5-b]benzothiophene (25) was synthesized by a different route. Fully assigned 1H and 13C nmr data of all new compounds are reported.

Enthalpy of formation for indazoles (indazole, 1H-indazole-3-carboxylic acid, 1H-indazole-5-carboxylic acid, 1H-indazole-6-carboxylic acid and 1-methyl-1H-indazole-6-carboxylic methyl ester): experimental and theoretical studies

The molar standard enthalpy of formation in condensed and gas phases of indazole, 1H-indazole-3-carboxylic acid, 1H-indazole-5-carboxylic acid, 1H-indazole-6-carboxylic acid and 1-methyl-1H-indazole-6-carboxylic methyl ester is reported. These properties were obtained indirectly from experimental determinations of the compounds using isoperibolic calorimetry and thermogravimetry. The values obtained for enthalpy of formation in the gas phase were compared with the computational results by means of the auxiliary density functional theory using deMon2k. The influence of the carbonyl and acetate groups on this type of compounds is analyzed energetically and structurally. The results obtained were compared and discussed with the data found in the literature.

Chiral Control in Pentacoordinate Systems: The Case of Organosilicates

Chirality at the central element of pentacoordinate systems can be controlled with two identical bidentate ligands. In such cases the topological Levi-Desargues graph for all the Berry pseudorotations (BPR, max. 20) reduces to interconnected inner and outer “circles” that represent the dynamic enantiomer pair. High enough barriers of the BPR crossovers between the two circles is all what is needed to ascertain chiral integrity. This is illustrated computationally and experimentally for the organosilicates 7 and 10 that carry besides a Me (a), Et (b), Ph (c), or F (d) group two bidentate 2-(phenyl)benzo[b]-thiophene or 2-(phenyl)naphthyl ligands, respectively. The enantiomers of tetraorganosilane precursor 9 could be separated by column chromatography. Their chiral integrity persisted on forming the silicates. CD spectra are reported for 10c. Fluoro derivative 10d is shown to have its electronegative F substituent in an equatorial position, is stable toward hydrolysis, and its enantiomers do not racemize at ambient temperatures, while those of 10c racemize slowly.

Bacterial transformations of benzothiophene and methylbenzothiophenes

The abilities of three Pseudomonas strains to transform each of the six isomers of methylbenzothiophene was studied. These compounds would not support growth but were biotransformed in a cell suspension of one of the isolates and in cultures of the other two isolates while they grew on 1- methylnaphthalene or glucose. Sulfur-containing metabolites were identified by GC/MS and GC/FTIR, and when possible, by comparison with authentic standards. Sulfoxides and sulfones were frequently detected and were the most abundant products from 2- and 3-methylbenzothiophene. Two of the isolates oxidized the methyl groups to carboxylic acids which were abundant products from 3-, 5-, and 6-methylbenzothiophenes. Benzothiophenemethanols were often detected, but in very low amounts. 2,3-Diones were observed as metabolites of benzothiophene and those methylbenzothiophenes with a methyl group on the benzene ring. Isomers of tolyl methyl sulfoxide were observed as ring cleavage products from 6- and 7-methylbenzothiophene.
