3-chloro-1-(4-iodophenyl)propan-1-ol, and 3-chloro-1-phenylpropan-1-ol is described. The procedure is based on the enantiomer-selective acylation of the racemic alcohols in presence of lipase from Pseudomonas fluorescens (LAK) followed by the lipase from Candida rugosa (CRL) mediated hydrolysis of previously obtained enantiomerically enriched 1-aryl-3-chloropropyl esters. For the production of enantiopure (S)-1-ar
脂肪酶催化3-氯-1-(4-氟苯基)丙-1-醇,3-氯-1-(4-碘苯基)丙-1-醇和3-氯-1-醇的两种对映体的合成描述了苯基丙-1-醇。该方法是基于在荧光假单胞菌(LAK)的脂肪酶存在下外消旋醇的对映异构体选择性酰化,然后是来自假丝酵母(CRL)的脂肪酶介导的先前获得的对映异构体富集的1-芳基-3-氯丙基酯的水解。对于生产对映纯(S)-1-芳基-3-氯丙烷-1-醇(99%ee,收率34-42%),以高于理论最佳50%的转化率停止反应,而对映纯([R)-1-芳基-3-氯丙基乙酸酯(99%ee)以较低的转化率停止反应。将后面的化合物酶水解为相应的(R)-1-芳基-3-氯丙烷-1-醇(97-99%ee,18-24%收率)。分辨率产品的绝对配置是通过VCD测量结合量子化学计算来确定的。 酶-动力学拆分-对映选择性-手性拆分-醇类-卤化物
