There is provided a novel method for producing an optically active (4R)-1,3-thiazolidine-4-carboxylic acid by allowing cells of a microorganism or a preparation obtained from cells of a microorganism having activity for stereoselectively hydrolyzing an optically active (4R)-1,3-thiazolidine-4-carboxylic acid amide to act on a mixture of (4R)- and (4S)-enantiomers of a 1,3-thiazolidine-4-carboxylic acid amide to produce the optically active (4R)-1,3-thiazolidine-4-carboxylic acid and separating the optically active (4R)-1,3-thiazolidine-4-carboxylic acid.
本发明提供了一种生产光学活性(4R)-1,3-噻唑烷-4-羧酸的新方法,该方法允许具有立体选择性水解光学活性(4R)-1、3-噻唑烷-4-羧酸酰胺作用于 1,3-噻唑烷-4-羧酸酰胺的(4R)-和(4S)-对映体混合物,生成光学活性的(4R)-1,3-噻唑烷-4-羧酸,并分离光学活性的(4R)-1,3-噻唑烷-4-羧酸。
