Stereoselective reduction of alkyl 3-oxobutanoate by carbonyl reductase from Candida magnoliae
摘要:
The enantioselective reduction of alkyl 3-oxobutanoates by carbonyl reductase (Sl) from Candida magnoliae was investigated. S1 reduced alkyl 4-halo-3-oxobutanoates to the corresponding enantiomerically pure (S)-3-hydroxy esters. Escherichia coli HB101 transformant co-overproducing the S1 and glucose dehydrogenase from Bacillus megaterium, produced optically pure alkyl 4-substituted-3-hydroxybutanoates in a two-phase water/organic solvent system.

relied on the availability of diverse starting materials prepared by traditional chemical synthesis methods. Here the synthesis of all acyclic dicarbonyl compounds and α-aminoketones used in the prior prebiotic model studies is described. There are five sets of acyclic dicarbonyl compounds including (i) β-ketoesters bearing diverse 4-substituents, (ii) levulinic acid derivatives bearing selected 5-substituents
