  Design and synthesis of hydrophobic, bulky χ2-constrained phenylalanine and naphthylalanine derivatives

  摘要：

  A series of novel hydrophobic, bulky chi(2)-constrained phenylalanine and naphthylalanine derivatives were designed and synthesized. Asymmetric hydrogenations of alpha-enamides using Burk's DuPHOS-based Rh(I) catalysts generated high enantiomerically pure alpha-amino acid derivatives, which subsequently underwent Suzuki cross couplings with boronic acid derivatives to afford these aromatic Substituted amino acids in high yields and with high enantioselectivity.

  A series of novel hydrophobic, bulky chi(2)-constrained phenylalanine, naphthylalanine, and tryptophan derivatives was designed and synthesized. The key steps involved asymmetric hydrogenations of alpha-enamides using Burk's DuPHOS-based Rh(l) catalysts to give high enantiomerically pure alpha-amino acid derivatives. The subsequent Suzuki cross couplings of the amino acid analogues with boronic acid derivatives afforded these aromatic substituted amino acids in high yields and with high enantioselectivity. The incorporation of these novel chi(2)-constrained amino acids into peptides and peptidomimetics provides fruitful information in the development of peptide and peptidomimetic ligands of melanotropins and an understanding of the interactions between ligands and receptors/acceptors.
