kinetic resolution mediated by Amano AK lipase from Pseudomonas fluorescens immobilized in silk friboin-alginate spheres. Thus, the enantioselectivity of the process was sufficient for the production of the desired alcohols and acetates in good yields and high enantiomeric purities. This Letter provides a simple, cheap, and practical protocol for enantioselective synthesis of chlorohydrins and reinforces
选择含氯醇基团的芳族,烯丙基和脂族化合物作为底物,用于由固定在丝素-海藻酸盐球体中的荧光假单胞菌的Amano AK脂肪酶介导的酶促动力学拆分。因此,该方法的对映选择性足以以高收率和高对映体纯度生产所需的醇和乙酸酯。该信为氯醇的对映选择性合成提供了一种简单,廉价和实用的方案,并增强了丝素蛋白作为多相催化剂载体的多功能性。
