One‐Pot Cascade Synthesis of (3S)‐Hydroxyketones Catalyzed by Transketolase via Hydroxypyruvate Generated in Situ from d‐Serine by d‐Amino Acid Oxidase


We described an efficient in situ generation of hydroxypyruvate from d‐serine catalyzed by a d‐amino acid oxidase from Rhodotorula gracilis. This strategy revealed an interesting alternative to the conventional chemical synthesis of hydroxypyruvate starting from toxic bromopyruvate or to the enzymatic transamination from l‐serine requiring an additional substrate as amino acceptor. Hydroxypyruvate thus produced was used as donor substrate of transketolases from Escherichia coli or from Geobacillus stearothermophilus catalyzing the stereoselective formation of a carbon−carbon bond. The enzymatic cascade reaction was performed in one‐pot in the presence of d‐serine and appropriate aldehydes for the synthesis of valuable (3S)‐hydroxyketones, which were obtained with high enantio‐ and diastereoselectivity and in good yield. The efficiency of the process was based on the irreversibility of both reactions allowing complete conversion of d‐serine and aldehydes.
