calculations described in our previous work. This P‐stereogenic bisphosphine ligand possessing a biphenyl backbone and 2,2′‐tert‐butylmethylphosphino groups has been applied to the Rh‐catalyzed asymmetric hydrogenation of enol esters, which has not been widely studied and can be used for the synthesis of several important bioactive compounds. Although there is room for further improvement in enantioselectivity
这是我们先前有关Atropos
联苯双
膦配体开发的工作的更新。单晶X射线衍射证实了Atropos出乎意料的结构性能,该结果与我们先前工作中所述的计算结果相符。这种具有
联苯骨架和2,2'-叔丁基
甲基膦基的P-stereogenic bisphosphine
配体已被用于Rh催化的烯醇酯的不对称加氢反应,尚未得到广泛研究,可用于合成几种重要的
生物活性化合物。尽管在对映选择性方面仍有进一步改进的余地,但本文报道的结果提供了对这类
配体的进一步理解。
