Kinetic resolution is a widely used strategy for separation and enrichment of enantiomers. Using density functional theory computations, the origin of how a chiral BINOL–phosphoric acid catalyzes the selective lactonization of one of the enantiomers of α-methyl γ-hydroxy ester is identified. In a stepwise mechanism, the stereocontrolling transition state for the addition of the hydroxyl group to the
动力学拆分是广泛使用的分离和富集对映异构体的策略。使用密度泛函理论计算,确定了手性BINOL-
磷酸如何催化α-甲基γ-羟基酯对映体之一的选择性内酯化的起源。在逐步机理中,在S异构体的情况下,向酯羰基的si表面加羟基的立体控制过渡态表现出底物和手性催化剂之间更有效的非共价相互作用的网络。
