Asymmetric benzoin reaction catalyzed by benzoylformate decarboxylase
摘要:
Aromatic aldehydes are converted into benzoins by benzoylformate decarboxylase catalyzed C-C bond formation. The reaction affords (R)-benzoins with high enantiomeric excess and in good chemical yields. A broad range of aromatic aldehydes can be used as substrates in aqueous buffer or buffer/DMSO-solutions.

Fourteen chiral α- and β-keto alcohols 2a–2r were synthesized by the asymmetric reduction of their corresponding diketones 1a–1r viabaker’s yeast. In addition, ten corresponding racemic α-keto alcohols were synthesized by the benzoin condensation of their corresponding aldehydes, which were used for the determination of the ee values through their chiral resolution on chiral HPLC. Amongst the 15 diketones
