• Enantioselective Copper(II)-Catalyzed Conjugate Addition of Indoles to β<i>-</i>Substituted Unsaturated Acyl Phosphonates
  作者：Hong-Li Ma、Lei Xie、ZhenHua Zhang、Jia-Qi Li、Zhao-Hai Qin、Bin Fu

  DOI：10.1002/adsc.201500923

  日期：2016.3.31

  The first copper‐catalyzed enantioselective conjugate addition of indoles to β‐substituted unsaturated acyl phosphonates was successfully realized by using a heteroarylidene‐tethered bis(oxazoline) ligand. The reaction features high efficiency, cheap catalyst and broad generality. In the case of either β‐alkyl‐ or β‐aryl‐substituted unsaturated acyl phosphonates, the 3‐indolyl adducts were achieved

• Catalytic and asymmetric Friedel–Crafts alkylation of indoles with nitroacrylates. Application to the synthesis of tryptophan analogues

  日期：2007.6

  An asymmetric Friedel–Crafts alkylation of indoles with nitroacrylates catalyzed by chiral (4R,5S)-DiPh-BOX (L1)–Cu(OTf)2 complex (10 mol %) has been developed. The reactions provide tryptophan nitro-precursors in moderate diastereoselectivities (anti/syn up to 72:28) and good to excellent enantioselectivities (up to 99% ee). The alkylation products could be easily reduced to optically active tryptophan

• Controllable Enantioselective Friedel−Crafts Reaction¹ between Indoles and Alkylidene Malonates Catalyzed by Pseudo-<i>C</i>₃-Symmetric Trisoxazoline Copper(II) Complexes
  作者：Jian Zhou、Meng-Chun Ye、Zheng-Zheng Huang、Yong Tang

  DOI：10.1021/jo035552p

  日期：2004.2.1

  Pseudo-C-3-symmetric trisoxazoline copper(II) complexes prove to be excellent catalysts in the Friedel-Crafts alkylation of indoles with alkylidene malonates. The absolute stereochemistry of this reaction is shown to be dependent on the solvent. Reactions in isobutyl alcohol afford the Friedel-Crafts alkylation adducts in excellent yields and with up to +98% ee. In 1,1,2,2-tetrachloroethane (TTCE), however, the opposite enantiomers of the products are obtained in good yields with up to -89% ee. Water tolerance of chiral catalyst trisoxazoline 2a/Cu(OTf)(2) is examined, and it is found that the addition of up to 200 equiv of water relative to catalyst in isobutyl alcohol has almost no effect on enantioselectivity but slows down the reaction. The reaction scope is studied as well. The roles of alcohol as the solvent to accelerate the reaction are discussed. The stereochemical models of asymmetric induction for reactions both in isobutyl alcohol and in TTCE are also developed.
• Asymmetric Friedel–Crafts alkylation of indoles with 2-nitro-3-arylacrylates catalyzed by a metal-templated hydrogen bonding catalyst
  作者：Jingfen Liu、Lei Gong、Eric Meggers

  DOI：10.1016/j.tetlet.2015.06.046

  日期：2015.8

  An asymmetric Friedel-Crafts alkylation of indoles with 2-nitro-3-arylacrylates catalyzed by a metal-templated hydrogen bonding catalyst has been established. The asymmetric induction relies on chirality transfer solely from the octahedral metal stereocenter via three weak hydrogen bonds. All the products are provided with good to excellent enantioselectivities while modest diastereoselectivities, which can be converted into a variety of valuable indole-containing chiral building blocks including tryptophan derivatives.
