The catalytic performance of the partially purified reductase was examined, and the highest activity was observed at pH 6.5 and 50 °C. The short-chain alkyl aldehydes such as acetaldehyde and those aldehydes or ketones with a benzoyl group were found to be good substrates for the reductase. ...
The current methodology substantiates a promising and alternative green approach for the synthesis of secondary chiral alcohols of biological importance in a mild, cheap and environmentally benign process.Keywords: Plant cell suspension culture,(S)-1-arylethanols,arylketones,enantioselective bioreduction,...

Reduction of α,β-unsaturated ketones generally can give rise to a variety of products, of which chiral allylic alcohols (1,2-reduction) and saturated ketones (1,4-reduction) are the most useful from the synthetic point of view. With the appropriate substitution pattern these processes generate...
If metalloenzymes could react through abiotic intermediates like these, then the scope of enzyme-catalysed reactions would expand. Here we show that zinc-containing carbonic anhydrase enzymes catalyse hydride transfers from silanes to ketones with high enantioselectivity. We report mechanistic data ...

The electrochemical reduction of several aryl α,β-unsaturated ketones, 1, has been studied at mercury cathodes by the techniques of polarography, controlled potential coulometry, and cyclic voltammetry. Conditions have been established under which the dimer, 2, formed by coupling at the β carbon ...
