• Asymmetric Conjugate Addition of Silyl Enol Ethers Catalyzed by Tethered Bis(8-quinolinolato) Aluminum Complexes

  aluminum(III) complexes effectively catalyze the highly enantioselective Mukaiyama−Michael reaction of silyl enol ethers, including tetrasubstituted enolates that give rise to enantioenriched α-carbonyl all-carbon-substituted quaternary stereocenters. The present catalyst also promotes the conjugate addition of N-benzylindole to α,β-unsaturated acylphosphonates with high enantioselectivity (indole Friedel−Crafts

  新的手性系链双（8-羟基喹啉）（TBOx）铝（III）配合物有效催化甲硅烷基烯醇醚的高度对映选择性 Mukaiyama-Michael 反应，包括产生对映体富集的 α-羰基全碳取代四元立体中心的四取代烯醇化物。本催化剂还促进了 N-苄基吲哚与具有高对映选择性的 α,β-不饱和酰基膦酸酯的共轭加成（吲哚 Friedel-Crafts 烷基化反应）。
• Catalytic Enantioselective Friedel-Crafts Alkylation of Indoles with β,γ-Unsaturated α-Keto Phosphonates in the Presence of Chiral Palladium Complexes

  日期：2011.5

  The catalytic enantioselective Friedel―Crafts alkylation reaction promoted by chiral palladium complexes is described. The treatment of indoles with β,γ-unsaturated α-keto phosphonates under the mild reaction conditions afforded the corresponding Friedel―Crafts alkylation adducts with excellent enantioselectivities (up to 99% ee).

• Enantioselective Friedel−Crafts Alkylations Catalyzed by Bis(oxazolinyl)pyridine−Scandium(III) Triflate Complexes

  日期：2007.8.1

  The enantioselective Friedel-Crafts addition of a variety of indoles catalyzed by bis(oxazolinyl)pyridine-scandium(III) triflate complexes (Sc(III)-pybox) was accomplished utilizing a series of beta-substituted alpha,beta-unsaturated phosphonates and alpha,beta-unsaturated 2-acyl imidazoles. The acyl phosphonate products were efficiently transformed into esters and amides, whereas the acyl imidazole adducts were converted to a broader spectrum of functionalities such as esters, amides, carboxylic acids, ketones, and aldehydes. The sense of stereoinduction and level of enantioselectivity were found to be functions of the size of the substrate employed, the substitution on the ligand, and the catalyst loading. Molecular modeling of the catalyst with the bound substrates was performed based on the crystal structures of the catalyst complexes and the sense of stereoinduction observed in the addition reaction. Nonlinear effects over a range of catalyst concentrations implicate a mononuclear complex as the active catalyst.

  An enantioselective Friedel−Crafts alkylation with α,β-unsaturated 2-acyl imidazoles and electron-rich aromatic nucleophiles catalyzed by bis(oxazolinyl)pyridine−scandium(III) triflate complexes has been accomplished. These α,β-unsaturated 2-acyl imidazoles are effective electrophiles for the Friedel−Crafts reaction. The resulting adduct 2-acyl imidazole is easily converted to amides, esters, carboxylic
