  Enantioselective synthesis of 3,5-disubstituted thiohydantoins and hydantoins

  摘要：

  A mild method to convert optically pure amino acid thiourea and urea derivatives to thiohydantoins and hydantoins, respectively, is described. It provides an efficient way to realize enantioselective synthesis of thiohydantoins and hydantoins with good to high isolated yields and enantiomeric purities. We found that the enantiomeric purities were highly dependent on the reaction conditions including bases, solvents, and temperature. (C) 2015 Elsevier Ltd. All rights reserved.

  with a range of unprotected side chains of amino acid. The ability to produce amide or peptides by a traceless removal of the auxiliary is a significant virtue of the method. Meanwhile, the application of this new peptide-bond-forming reaction to the synthesis of novel endomorphin (EM) derivatives with various binding potencies was realized.

  已经设计出一种新颖且无痕的策略，其允许将硫代酸和二硫代氨基甲酸酯末端的胺偶联。在较早的天然化学连接方法中，已假定该策略取决于半胱氨酸侧链功能等同物的附着。这种方法能够无痕地去除CS 2以直接生成所需的酰胺键，并且与一系列未保护的氨基酸侧链兼容。通过无痕去除助剂产生酰胺或肽的能力是该方法的重要优点。同时，实现了这种新的肽键形成反应在具有各种结合力的新型内啡肽（EM）衍生物的合成中的应用。
