  Chiral Nβ-Fmoc-amino alkyl isonitriles in Ugi-4CR: an assembly of novel 1,1′-iminodicarboxylated peptidomimetics

  摘要：

  Enantiopure N-beta-Fmoc-amino alkyl isonitriles and amino acid esters have been employed as building blocks in Ugi four-component reaction (U-4CR) to yield 1,1 '-iminodicarboxylated peptidomimetics. By employing trifluoroacetic acid as one of the components, a different outcome has been observed and rationalized. Ugi products are obtained as trifluoroacetamide adducts, which on further reaction under mild acidic conditions lead to the title compounds. The method has also been proven to be useful for the preparation of ethyl, benzyl and tert-butyl esters. (C) 2011 Elsevier Ltd. All rights reserved.

  Synthesis of β-lactam peptidomimetics through Ugi MCR: first application of chiral Nβ-Fmoc amino alkyl isonitriles in MCRs

  摘要：

  Chiral N-beta-Fmoc amino alkyl isonitriles were employed in Ugi multi component reactions (Ugi 4C-3CR) to obtain functionalized beta-lactam peptidomimetics with L-aspartic acid alpha-methyl ester/peptide ester and organic aldehydes. The reactions were carried out in MeOH. Thirteen Ugi products have been prepared in good to moderate yields with good diastereoselectivities. (C) 2011 Elsevier Ltd. All rights reserved.

  The Ugi-4C reaction employing Nβ-protected-amino alkyl isonitrile, amino acid ester, aldehyde, and glycosyl acid has resulted in novel glycosylated peptidomimetics. The extension of MCR products for the synthesis of N,N′-orthogonally protected glycosylated peptidomimetics has also been demonstrated.

  A novel class of optically active N-Fmoc-protected amino isonitriles has been described for the first time. Conversion of the carboxyl group of Fmoc-β-amino acids into an isocyano group has resulted in a new class of N-urethane-protected amino isonitriles. All the isonitriles have been isolated as stable solids, purified, and completely characterized. A synthetic application of the obtained isonitriles

  首次描述了一类新型的具有光学活性的N -Fmoc保护的氨基异腈。Fmoc-β-氨基酸的羧基转化为异氰基导致了新型的N-氨基甲酸酯保护的氨基异腈。所有的异腈均已分离为稳定的固体，经过纯化并进行了完全鉴定。通过与三甲基甲硅烷基叠氮化物通过2 + 3环加成反应合成氨基酸的1-取代的四唑类似物，也证明了所获得的异腈的合成应用。
