The enzyme-catalyzed asymmetric hydrolysis of the meso-diesters derived from cis-2,5-bis(hydroxymethyl)tetrahydrofuran in presence of PLE, PPL, and CCL afforded the optically active half-esters. The both enantiomers of cis-5-(hydroxymethyl)tetrahydrofuran-2-carboxylic acid with high optical purity were prepared from the half-esters.
在PLE、PPL和CCL存在的情况下,由顺式-2,5-双(羟甲基)四氢呋喃衍生的中位二酯通过酶催化不对称水解,得到具有光学活性的半酯。从半酯中制备出具有高光学纯度的顺式-5-(羟甲基)四氢呋喃-2-羧酸的两种对映异构体。
