A highly efficient and mild Cu-catalyzed conjugate addition reaction of aromaticamines and aromatic aza-heterocycles to α,β-unsaturated olefins is described. The transformation is promoted by 3–7 mol % of a Cu complex generated in situ from a mixture of inexpensive CuCl, a readily available phosphine or imidazolium salt, and KOt-Bu at ambient temperature. A wide range of β-amino sulfone, β-amino nitrile
描述了芳族胺和芳族氮杂杂环对α,β-不饱和烯烃的高效且温和的Cu催化的共轭加成反应。在环境温度下,由廉价的CuCl,易得的膦或咪唑鎓盐和KO t -Bu的混合物原位生成的3–7 mol%的Cu络合物促进了这种转变。可以高效,有选择地合成大量β-氨基砜,β-氨基腈和β-氨基羰基化合物(62–99%)。
