Highly efficient and practical aerobic oxidation of alcohols by inorganic-ligand supported copper catalysis

The oxidation of alcohols to aldehydes or ketones is a highly relevant conversion for the pharmaceutical and fine-chemical industries, and for biomass conversion, and is commonly performed using stoichiometric amounts of highly hazardous oxidants. The aerobic oxidation of alcohols with transition metal complex catalysts previously required complicated organic ligands and/or nitroxyl radicals as co-catalysts. Herein, we report an efficient and eco-friendly method to promote the aerobic oxidation of alcohols using an inorganic-ligand supported copper catalyst 1, (NH4)4[CuMo6O18(OH)6], with O2 (1 atm) as the sole oxidant. Catalyst 1 is synthesized directly from cheap and commonly available (NH4)6Mo7O24·4H2O and CuSO4, which consists of a pure inorganic framework built from a central CuII core supported by six MoVIO6 inorganic scaffolds. The copper catalyst 1 exhibits excellent selectivity and activity towards a wide range of substrates in the catalytic oxidation of alcohols, and can avoid the use of toxic oxidants, nitroxyl radicals, and potentially air/moisture sensitive and complicated organic ligands that are not commercially available. Owing to its robust inorganic framework, catalyst 1 shows good stability and reusability, and the catalytic oxidation of alcohols with catalyst 1 could be readily scaled up to gram scale with little loss of catalytic activity, demonstrating great potential of the inorganic-ligand supported Cu catalysts in catalytic chemical transformations.

Synthesis of Analogues of 1,3-Dihydroxyacetone Phosphate and Glyceraldehyde 3-Phosphate for Use in Studies of Fructose-1,6-diphosphate Aldolase

This paper describes the synthesis of five analogues of dihydroxyacetone phosphate (3-azidohydroxyacetone 1-phosphate (5), 3-(acetylamino)hydroxyacetone 1-phosphate (12), (R)-1,3-dihydroxy-2-butanone 1-phosphate (18), (+/-)-1,3-dihydroxy-2-butanone 3-phosphate (26), and phosphonomethyl glycolate (31)).The syntheses of 18 and 26 are based on a new reaction: that is, the introduction of the phosphate group by the reaction of a diazo ketone with dibenzyl phosphate.These methods provide easy access to a number of compounds that are potential substrates for the synthetically useful enzyme aldolase (fructose-1,6-diphosphate aldolase from rabbit muscle, EC 4.1.2.13, RAMA) and perhaps for other enzymes of glycolysis.This paper also describes syntheses of 14 aldehydes for examination as substrates for aldolase.When the precursor was available, ozonolysis of vinyl groups proved to be the best route to the corresponding aldehydes.

Thiohemiacetal formation by inhibitory aldehydes at the active site of papain.

Papain is strongly inhibited by aldehydes resembling carboxylic acids, released by hydrolysis of specific substrates (Westerik, J. O''C., and Wolfenden, R. (1972), J. Biol. Chem. 247, 8195-8197). Inhibitory complexes might involve binding of the aldehyde intact or as a covalent hydrate, or the aldehyde might undergo covalent addition of an active site sulfhydryl group to form a thiohemiacetal derivative. In an attempt to distinguish between these possibilities, benzamidoacetaldehyde-1-d has been synthesized, and its properties compared with those of the undeuterated inhibitor. After correction for differences in hydration, the observed effect on inhibition is found to be compatible with formation of a thiohemiacetal. In keeping with this conclusion, benzamidoethanol (a partial analogue of the covalent hydrate) and benzamide, N-methylbenzamide and N-ethylbenzamide (somewhat similar to the free aldehyde in size and hydrophobic character) are found to exhibit negligible affinity for the active site.
