(S)-malic, (R)citramalic, (S)-citramalic, (2R,3S)-2-hydroxy-3-methyl-succinic and (2R,3S)-2,3-dimethyl-2-hydroxysuccinic acid were prepared on scales up to 25 mmol by stereospecific addition of water to different 2-butene-1,4-dioic acid derivatives catalyzed by resting cells of Clostridium formicoaceticum (Scheme 1). The (3R)-monodeuterio (R)- and (S)-malic acid as well as (R)- and (S)-citramalic acid were
(R)-苹果酸,(S)-苹果酸,(R)柠檬酸,(S)-柠檬酸,(2 R,3 S)-2-羟基-3-甲基-琥珀酸和(2 R,3 S)-2通过将水立体定向加成到不同的2-丁烯-1,4-二酸衍生物中,由梭状梭状芽孢杆菌的静止细胞催化,可制备高达25 mmol的规模的3-3-二甲基-2-羟基琥珀酸(方案1)。的(3 - [R)-monodeuterio([R )-和(小号) -苹果酸,以及(- [R )-和(小号)-citramalic苯甲酸用冷冻干燥的细胞中制备的2H 2 O缓冲区。在大多数情况下,产品的立体化学纯度均≥99%。
