A new chemo-enzymatic route to both isomers of 2-hydroxy-4-phenylbutyric acid is reported. The key step is the lactonase-catalyzed hydrolysis of cis- and trans-2-hydroxy-4-phenyl-4-butyrolactones followed by hydrogenation over Pd/C to afford optically pure 2-hydroxy-4-phenylbutyric acid.

化学酶法合成两种异构体的
2-羟基-4-苯基丁酸。关键步骤是通过
乳酮酶催化对顺式和反式2-羟基-4-苯基-4-丁内酰胺的
水解,随后在Pd/C上进行氢化,以获得光学纯的
