• <i>N</i>-Trialkylsilyl Bistrifluoromethanesulfonimides (R₃SiNTf₂) Are Powerful Catalysts for the Highly Efficient α-Amido Alkylation Reactions of Silicon-Based Nucleophiles

  DOI：10.1021/ol052357j

  日期：2005.11.1

  In situ formed N-trialkylsilyl bistrifluoromethanesulforlimides (R3SiNTf2) species have been shown to efficiently catalyze the nucleophilic substitution reactions of chiral 5-oxypyrrolidin-2-ones by silicon-based nucleophiles. The reaction rates were significantly accelerated in comparison to the cases where the usual triflate catalysts are used. Adducts were obtained in high yields and usual stereoselectivities within short reaction times, and the process was compatible with a semipreparative scale.

• Toward Improving the Chemistry of <i>N</i>-Acyliminium Ions:  Nucleophilic Substitution Reactions of Pyrrolidinone Derivatives with Trialkylsilyl Nucleophiles Catalyzed by Triisopropylsilyltrifluoromethane Sulfonate (TIPSOTf)
  作者：Raja Ben Othman、Till Bousquet、Anthony Fousse、Mohamed Othman、Vincent Dalla

  DOI：10.1021/ol050576z

  日期：2005.7.1

  Nucleophilic substitution reactions of racemic and chiral 5-acetoxy-, 5-ethoxy-, and 5-methoxypyrrolidin-2-ones by silicon-based nucleophiles were efficiently catalyzed by TIPSOTf. This process was found to be general and accommodates a broad range of substrate-nucleophile combinations.
• Addition of silylated carbon nucleophiles to iminium and cyclic N-acyliminium ions promoted by InCl3

  日期：2000.12

  InCl3 was used as Lewis acid in the addition of silyl enolates and allyltrimethylsilane to aromatic aldimines and cyclic N-acyliminium ions derived from 5-acetoxylactams affording beta -aminocarbonyl systems and allyl adducts, respectively, in reasonable to good yields. The diastereofacial selectivity of cyclic N-acyliminium ions was investigated. (C) 2000 Elsevier Science Ltd. All rights reserved.
