  摘要：

  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。

  A new facile synthetic route to prepare N-glycosylamino acids in fewer steps is reported. 5-Oxazolidinone served as an effective protecting moiety for NI±-Fmoc-Asp/Glu and after glycosylation, the ring opening resulted in free I±-carboxylic acid, which can be directly used to extend the chain to obtain N-glycopeptides. Both the minimum number of steps as well as circumvention of orthogonal protection

  报道了一种以较少步骤制备 N-糖基氨基酸的新合成路线。5-恶唑烷酮作为NI±-Fmoc-Asp/Glu的有效保护部分，糖基化后开环产生游离的I±-羧酸，可直接用于扩链得到N-糖肽。最少的步骤数以及规避正交保护策略都为它们的合成提供了一种具有成本效益的途径。该协议可以很容易地扩大规模，以相当好的产量大量制备 N-糖基化 Asn/Gln 酸。© Georg Thieme Verlag 斯图加特。

  A simple and efficient one-pot synthesis of Fmoc/Boc/Z-amino acid derived 2-amino-1,3-selenazoles by the condensation of NI±-urethane protected amino acid derived bromomethyl ketones with selenourea under the influence of ultrasound has been described. Insertion of 2-amino-1,3-selenazole moiety in the side chains of Asp and Glu has also been achieved following the similar protocol. © ARKAT USA, Inc

  The present inventors have found that when screening for cyclic peptide compounds that can specifically bind to a target molecule, the use of a library including cyclic peptide compounds having a long side chain in the cyclic portion can improve the hit rate for cyclic peptide compounds that can specifically bind to the target molecule. Meanwhile, the present inventors have found that tryptophan and tyrosine residues, which have conventionally been used in oral low molecular-weight pharmaceuticals and are amino acid residues having an indole skeleton or a hydroxyphenyl group, are not suitable for peptides intended to attain high membrane permeability.

  本发明人发现，在筛选能与目标分子特异性结合的环肽化合物时，使用包括环状部分具有长侧链的环肽化合物库，可以提高能与目标分子特异性结合的环肽化合物的命中率。同时，本发明者发现色氨酸和酪氨酸残基不适合用于旨在获得高膜渗透性的肽，这两种残基通常用于口服低分子量药物，是具有吲哚骨架或羟基苯基的氨基酸残基。

  [Graphics]Reaction of 96% formic acid with isocyanates derived from N-Fmoc alpha-amino acids/peptide acids catalyzed by DMAP has yielded a new class of stable formamides as crystalline solids which have been characterized by IR, H-1 NMR, C-13 NMR, and mass spectroscopy. Conversion of the side chain carboxylic acid of N-Fmoc-5-oxazolidinones of Asp/Glu into the N-formyl group also has been accomplished. The reaction is simple, mild, and high yielding.
