The first highly chemo- and enantioselective hydrogenation of α,β-disubstituted nitroalkenes was accomplished with rhodium/JosiPhos-J2 as a catalyst, with the yield and enantioselectivity of up to 95% and 94%, respectively. The α-chiral nitroalkanes will provide an entry to valuable chiral amphetamines which are otherwise not so easily accessed.
以铑/JosiPhos-J2 为催化剂,首次实现了δ、δ²-二取代硝基烯烃的高度化学和对映选择性氢化,产率和对映选择性分别高达 95% 和 94%。δ-手性硝基烷烃将为获得珍贵的手性安非他明提供一个途径,而这些手性安非他明并不容易获得。
