    摘要: An optically active 2-hydroxy acid derivative is produced by treating a 2-oxo acid derivative with a microorganism, which has been optionally treated, capable of asymmetrically reducing said 2-oxo acid derivative into an optically active (R)- or (S)-2-hydroxy acid derivative represented by the formula (II) and recovering the optically active (R)- or (S)-hydroxy acid derivative thus formed. Optically active 2-hydroxy acid derivatives are important intermediates in the synthesis of various drugs such as a remedy for hypertension.
