  Condensations based on 5-(indol-3-yl)-pyrrolidin-2-thiones

  摘要：

  AbstractNew activated indolylpyrrolidones—their methylthiopyrrolinium salts—in the reactions with several CH‐acids were studied. 2‐Nitromethylene‐ and 2‐dicyanomethyleneindolylpyrrolidines were obtained from 5‐indolyl‐2‐methylthiopyrrolinium salts with good yields. The reduction in these nitro compounds yields the respective aminomethylpyrolidines. The rigid structure of the starting compounds has significant stereoelectronic requirements of nucleophilic agents.

  Tandem Ring-Closing Metathesis/Isomerization Reactions for the Total Synthesis of Violacein

  摘要：

  A series of 5-substituted 2-pyrrolidinones was synthesized through a one-pot ruthenium alkylidene-catalyzed tandem RCM/isomerization/nucleophilic addition sequence. The intermediates resulting from RCM/isomerization showed reactivity toward electrophiles in aldol condensation reactions which provided a new entry for the total synthesis of the antileukemic natural product violacein.

• Enantioselective, Thiourea-Catalyzed Intermolecular Addition of Indoles to Cyclic N-Acyl Iminium Ions

  日期：——

  Fair game for indoles, N‐acyl iminium ion intermediates underwent intermolecular addition by these nucleophiles under the catalysis of a chiral thiourea Schiff base derivative. A variety of functionalized indole frameworks were assembled with high enantioselectivity from simple precursors by this method (see scheme; TMS=trimethylsilyl; R=H, Me, vinyl, OMe, F, Cl, Br; R1=benzyl, methyl; n=1,2).

  The reduction of activated 5-(indol-3-yl)pyrrolidin-2-ones leading to a mixture of the respective indolyl pyrrolidines and their borane complexes, as well as several other transformations indicate that the electrophilicity of carbonyl group in 5-indolylpyrrolidin-2-ones is significantly decreased.

  The reaction under mild conditions of 1-alkyl-5-hydroxypyrrolidin-2-ones with different indoles having a free 3 position leads exclusively to 1-alkyl-5-(indol-3-yl)pyrrolidin-2-ones but if position 3 is occupied to 1-alkyl-5-(indol-2-yl)pyrrolidin-2-ones.
