The first highly enantioselective Cu -catalyzed azide-alkyne cycloaddition (CuAAC) of tertiary alcohols and their kinetic resolution is reported. This approach allows facile access to multifunctional tertiary alcohols featuring an α-ethynyl or α-triazole moiety, and represents the first successful kinetic resolution of racemates with a tetrasubstituted carbon stereocenter via CuAAC. Newly developed pyridinebisoxazoline (PYBOX) ligands with a C4 phosphonate group play a key role.
报道了首例叔醇的高度对映选择性铜催化叠氮化物-炔烃环加成反应（CuAAC）及其动力学拆分。该方法能够方便地获得具有α-乙炔基或α-三唑部分的多功能叔醇，并且代表了通过CuAAC对具有四取代碳立体中心的外消旋体进行的首次成功动力学拆分。新开发的带有C4膦酸酯基团的吡啶双恶唑啉（PYBOX）配体起到了关键作用。
