The reactions are catalyzed by chiral copper(II) complexes, and MnO2 is used as the inexpensive stoichiometric oxidant. A variety of five-membered heterocycles and a tetrahydroisoquinoline have been synthesized in good to excellent yields with good to excellent levels of enantioselectivity. This is the first reported copper-catalyzed enantioselective carboamination of alkenes.
介绍了用于合成氮杂环的 γ-烯基芳基磺酰胺和 δ-烯基芳基磺酰胺的对映选择性氧化环化。该反应由手性铜 (II) 配合物催化,MnO2 用作廉价的化学计量氧化剂。各种五元杂环和四氢异喹啉已以良好至极好的收率和良好至极好的对映选择性水平合成。这是首次报道的铜催化烯烃的对映选择性碳胺化。
