  Ag-Catalyzed Diastereo- and Enantioselective Synthesis of β-Substituted Tryptophans from Sulfonylindoles

  摘要：

  The asymmetric catalytic synthesis of beta-substituted tryptophan derivatives was realized in high diastereo- and enantioselectivity by the reaction of glycine derivatives with sulfonylindoles in the presence of catalyst derived from AgCl and a commercially available chiral monodentate phosphoramidite ligand. The resulting adduct was readily converted to beta-substituted tryptophan in 95% overall yield for two steps, which presented a highly efficient route to chiral beta-substituted tryptophan.

  Solventless Clay-Promoted Friedel−Crafts Reaction of Indoles with α-Amido Sulfones:  Unexpected Synthesis of 3-(1-Arylsulfonylalkyl) Indoles

  摘要：

  Friedel-Crafts reaction of indoles with alpha-amido sulfones in the presence of montmorillonite K-10 leads unexpectedly to 3-(1-arylsulfonylalkyl) indoles in good yield. The obtained products can be further desulfonylated under reductive or alkylative conditions giving linear and branched 3-substituted indoles.

This methodology tolerates a broad scope of 2-unsubstituted sulfonyl indoles, which have seldom achieved high enantioselectivities in similar asymmetric reactions with other nucleophiles. Chiral 3-sec-alkyl-substituted indoles containing α-diazophosphonate were afforded

  The asymmetric synthesis of syn-beta-substituted tryptophan derivatives was carried out by the Michael addition of chiral equivalent of nucleophilic glycine with sulfonylindoles, and high diastereo- and enantioselectivities were achieved. The resulting adducts were readily converted to syn-beta-substituted tryptophans in 96% yield, indicating that the proposed method is a highly efficient route to
