Bicyclo[2.2.1]heptene derivatives (1)–(3), building blocks for terpenoid natural products, have been prepared with high enantiometric purities by enzymatic hydrolysis of their racemic esters in the presence of porcine liver esterase (PLE) and an ester hydrolase from Pseudomonas sp. (SAM-II).
双环[2.2.1]庚烯衍生物(1)-(3)是萜类天然产物的组成部分,已通过在猪肝酯酶(PLE)和一种酯的存在下对其外消旋酯进行酶水解,以高对映体纯度制备假单胞菌(Pseudomonas sp)的水解酶。(SAM-II)。
