development of enantioselective C−H activation reactions by desymmetrization. However, the requirement for the presence of two chemically identical prochiral C−H bonds represents an inherent limitation in scope. Reported is the first example of kinetic resolution by a palladium(II)‐catalyzed enantioselective C−H activation and C−C bond formation, thus significantly expanding the scope of enantioselective C−H
Optically pure α-hydroxyacids and their derivatives are versatile chiral building blocks in the pharmaceutical industry. In this study, the potential of a recombinant Pseudomonas putida esterase (rPPE01) for the enzymaticresolution of α-acetoxy acids was significantly improved by combinatorial engineering of both the biocatalyst and substrate. Semirational design based on homologous modeling and
光学纯的α-羟基酸及其衍生物是制药工业中通用的手性结构单元。在这项研究中,生物催化剂和底物的组合工程显着提高了重组恶臭假单胞菌酯酶(rPPE01)对α-乙酰氧基酸进行酶促拆分的潜力。基于同源建模和分子对接的半理性设计提供了单点变体W187H,其对2-乙酰氧基-2-(2'-氯苯基)乙酸钠(Ac-CPA-Na)的k cat / K M增加了100-倍,从0.0611到6.20 mM –1 s –1,同时保留其出色的对映选择性和广泛的底物谱。通过使用Ac-CPA的钾盐代替Ac-CPA-Na可以减少操作条件下的生物催化剂失活。用0.5 g L –1的含有rPPE01-W187H的冻干细胞,在15 h内将500 mM(R,S)-Ac-CPA-K选择性脱酰基,转化率为49.9%,这两个S产物均得到令人满意的对映体过量(ee)(> 99%ee)和剩余的R底物(98.7%ee)。因此,(S与野生型酯酶的原
