一般說明

该产品是由 Pfaltz 及其同事引入的磷恶唑啉 (PHOX) 配体。这些不对称的模块 P,N-配体在双键迁移导致不需要的产物或异构体混合物的情况下特别有用。

應用

( S )-4--丁基-2-[2-(二苯基膦)苯基]-2-恶唑啉可用作对映选择性 Heck 反应的配体,无任何 C = C 双键迁移副产物。也可用于铑 (I) 催化的内消旋-3,5-二甲基戊二酸酐的对映选择性去对称反应,在单次转化中形成取代 -脱氧多丙酸酯碎片。

Andreas Pfaltz has a longstanding interest in the design of chiral ligands for asymmetric catalysis. The semicorrins developed in his group served as the prototype for an important family of nitrogen ligands, the bisoxazolines, which have found widespread use in catalytic asymmetric synthesis.
