addition of diarylphosphines with N-enoylbenzotriazoles and analogues is described. Chiral phosphine products are obtained in 100% atom economy and without cumbersome protection–deprotection manipulations. The obtained products can be subsequently transformed to bear various functionalities, including phosphino-carboxylic esters which play critical roles in catalysis and as synthetic aids.

催化加氢磷酸化反应是当今最可持续的化学转化之一。在此,描述了二芳基膦与N-烯酰基苯并三唑和类似物的钯催化的不对称PH加成。手性膦产品的原子经济性为100%,无需繁琐的保护-去保护操作。随后可以将获得的产物转化为具有各种功能,包括在催化中和作为合成助剂发挥关键作用的膦基羧酸酯。已经探索了相应的金膦复合物的抗肿瘤活性,为癌症治疗中的现有化学疗法研究做出了贡献。
