Amino acid thioesters used as substrates for a chemo-enzymatic dynamic kinetic resolution (DKR) must be designed with a high enough acidity to be rapidly racemized in the presence of a suitable base. Kinetic data obtained from experimental proton exchange rates are correlated with thermodynamic data for the proton abstraction based on the density functional theory (DFT) calculations. The good correlation
用作化学酶动力学动力学拆分(DKR)底物的氨基酸硫酯必须设计成具有足够高的酸度,以便在合适的碱存在下迅速消旋。根据密度泛函理论(DFT)计算,将从实验质子交换速率获得的动力学数据与质子提取的热力学数据相关联。获得的良好相关性允许评估不同官能团对碳酸度的贡献,并确定能够进行所需消旋作用的碱基。
