A class of axially chiral NHC–Au(I) complexes has been applied to the asymmetric Friedel–Crafts/cyclization reaction of nitrogen-tethered 1,6-enynes 14 with indole derivatives 15, affording the corresponding Friedel–Crafts and intramolecular cyclization products 16 in good yields and with moderate ee values under mild conditions.
一类轴向手性NHC-Au(I)络合物已被用于氮拴的1,6-炔烃14与吲哚衍生物15的不对称Friedel-Crafts /环化反应,提供了相应的Friedel-Crafts和分子内环化产物16在温和条件下具有良好的产量和适度的ee值。
