A highly enantioselective method for the complete hydrogenation of pyrimidinium salts using Ir/(S,S)-f-Binaphane complex as the catalyst was presented in this study. This approach affords facile access to a range of fully saturated chiral hexahydropyrimidines, which are prevalent in many bioactive molecules. The reactions showcase high yields and enantioselectivities under mild reaction conditions
本研究提出了一种使用 Ir/(S,S)-f-Binaphane 络合物作为催化剂来完全氢化嘧啶鎓盐的高度对映选择性方法。这种方法可以轻松获得一系列完全饱和的手性六氢嘧啶,它们在许多生物活性分子中普遍存在。该反应在温和的反应条件下无需添加剂即可表现出高产率和对映选择性。这种方法以连续流方式的成功应用进一步拓宽了其实用性。
