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。
