iodide catalyzed phosphine/aryl halide coupling procedure of Buchwald et al. provides modular, robust, and scaleable access to phosphinooxazoline (PHOX) ligands. The advantages of this method are highlighted by the convenient synthesis of PHOX ligands with varied steric and electronic properties, which would be challenging to synthesize by other protocols.
Buchwald等人的碘化铜(I)催化的膦/芳基卤化物偶联过程。提供了对膦氧恶唑啉(PHOX)配体的模块化,稳定且可扩展的访问方式。这种方法的优点是可以方便地合成具有变化的空间和电子特性的PHOX配体,这对其他方法很难合成。
