A highly efficient, iridium-catalyzed, enantioselective hydrogenation of β,β-disubstituted nitroalkenes has been developed. Using a complex consisting of iridium and (S,S)-f-spiroPhos as the catalyst, a variety of β,β-disubstituted nitroalkenes were successfully hydrogenated to the corresponding chiral nitroalkanes with excellent enantioselectivities (up to 98% ee) and high turnover numbers (TON=1000)
已经开发出高效的铱催化的β,β-二取代硝基烯烃的对映选择性氢化。使用由铱和(S,S)-f-spiroPhos组成的配合物作为催化剂,将多种β,β-二取代硝基烯烃成功氢化为相应的手性硝基烷,具有出色的对映选择性(高达98%ee)和高转化率数字(TON = 1000)。
