A high enantiomer-selectivity for the polymerization of rac-lactide was achieved using chiral binaphthol-derived monophosphoric acids as organocatalysts. During the polymerization, d-lactide (DLA) preferentially polymerized via kinetic resolution with the maximum selectivity factor (kD/kL) of 28.3. The selective polymerization of DLA was derived from a dual activation, i.e., monomer activation and chain-end activation.
手性联萘酚衍生的单磷酸作为有机催化剂实现了 rac-丙交酯聚合的高对映选择性。在聚合过程中，d-丙交酯（DLA）通过动力学拆分优先聚合，最大选择性因子（kD/kL）为 28.3。DLA 的选择性聚合源自双重活化，即单体活化和链端活化。
