The first intermolecular enantioselective addition of nitroalkanes to unactivated α,β-unsaturated esters is described, catalyzed by a bifunctional iminophosphorane (BIMP) superbase. This fundamental synthetically relevant transformation proceeds with high enantiomeric excesses and yields over a wide range of feedstock substrates, providing pharmaceutically relevant building blocks in a single step
描述了硝基烷烃与未活化的 α,β-不饱和酯的第一次分子间对映选择性加成,由双功能亚氨基正膦 (BIMP) 超强碱催化。这种基本的合成相关转化在多种原料底物上以高对映体过量和产率进行,只需一步即可提供药学相关的构建模块。
