enables the enantioselective synthesis of both building blocks starting from diketones. The enzyme 2,3-butanediol dehydrogenase (BudC) from S. marcescens CECT 977 belongs to the NADH-dependent metal-independent short-chain dehydrogenases/reductases family (SDR) and catalyses the selective asymmetric reductions of prochiral α-diketones to the corresponding α-hydroxy ketones and diols. BudC is highly active

Regio- and stereoselectivereductions of several diketones to afford enantiopure hydroxy ketones or diols were accomplished using isolated alcohol dehydrogenases (ADHs). Results could be rationalised taking into account different (promiscuous) substrate-binding modes in the active site of the enzyme. Furthermore, interesting natural cyclic diketones were also reduced with high regio- and stereoselectivity

α-Hydroxy alkanones were synthesised with high enantiomeric purity by stereoselective enzyme-catalysed diketonereduction. Both diketonereduction and cofactor regeneration were accomplished with purified carbonylreductasefromCandidaparapsilosis (CPCR2). The reaction products were isolated by column chromatography and analysed by chiral GC measurements, 1H-NMR spectroscopy and determination of
The invention relates to a process for the regioselective and enantioselective preparation of α-hydroxy carbonyl compounds from α-ketocarbonyl compounds via enzymatic reduction.
