We report the first highly selective kinetic resolution of racemic α-chiral azides by Cu-catalyzed azide-alkyne cycloadditions (CuAAC), providing facile access to chiral α-tertiary azides and 1,2,3-triazoles with newly developed PYBOX ligands with a C4 sulfonyl group. The key role of the C4 sulfonyl in tuning the electronic and steric properties of the chiral catalysts to enhance enantiomer discrimination
我们报告了通过 Cu 催化的叠氮化物-炔烃环加成 (CuAAC) 对外消旋 α-手性叠氮化物的首次高选择性动力学拆分,提供了通过新开发的 PYBOX 配体轻松获得手性 α-叔叠氮化物和 1,2,3-三唑C4磺酰基。DFT 计算合理化了 C4 磺酰基在调节手性催化剂的电子和空间特性以增强对映异构体区分方面的关键作用。
