  Isoselenocyanates derived from Boc/Z-amino acids: synthesis, isolation, characterization, and application to the efficient synthesis of unsymmetrical selenoureas and selenoureidopeptidomimetics

  摘要：

  Isoselenocyanates derived from Boc/Z-amino acids are prepared by the reaction of the corresponding isonitriles with selenium powder in presence of triethylamine at reflux. The utility of these new classes of isoselenocyanates in the preparation of selenoureidodipeptidomimetics possessing both amino as well as carboxy termini has been accomplished. The H-1 NMR analysis confirmed that the protocol involving the conversion of isonitriles to isoselenocyanates and their use as coupling agents in assembling selenour-eido derivatives is free from racemization.

  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.

  straightforward oxidative cross-coupling synthesis of carbodiimide tethered amino acid conjugates from amino acid-derived isocyanides and aryl amines mediated by I2/tert-butyl hydroperoxide. Using this protocol, the title compounds were obtained in good isolated yields. This protocol is of short reaction duration, base-free, racemization free and avoids the necessity of transition metal catalysts. Graphical Abstract

  摘要 在这项研究中，我们报道了由氨基酸衍生的异氰化物和芳胺在 I2/叔丁基氢过氧化物介导下直接氧化交叉偶联合成碳二亚胺系链氨基酸偶联物。使用该方案，以良好的分离产率获得了标题化合物。该协议反应时间短，无碱，无外消旋化，避免了过渡金属催化剂的必要性。图形概要
