  An improved practical synthesis of protected α-amino selenocarboxylates and its application to the synthesis of N-(α-aminoacyl)sulfonamides

  摘要：

  An improved practical synthetic method was developed for the preparation of selenocarboxylates of amino acids through the reaction of the corresponding activated esters with sodium hydrogen selenide in alcoholic or aqueous medium. The protected cc-amino selenocarboxylates reacted readily with sulfonyl azide to form N-(alpha-aminoacyl)sulfonamides in high yields. The commonly used protecting groups in amino acid and peptide chemistries are well tolerated under these reaction conditions. No protecting groups are needed for the side chains of Arg, Met, Set, Tyr, and Trp. (C) 2009 Published by Elsevier Ltd.

  日期：——

  Common protecting groups used in amino acid/peptide chemistry were all well-tolerated. The method was also successfully applied to the synthesis of a dipeptide conjugate, indicating that the methodology is applicable to the synthesis of chromogenic substrates containing short peptides. The method has general applicability to the synthesis of chromogenic and fluorogenic peptide substrates and represents

  氨基酰基对硝基苯胺 (aminoacyl-pNA) 和氨基酰基 7-amino-4-methylcoumarin (aminoacyl-AMC) 是合成显色/荧光蛋白酶底物的重要合成子。开发了一种新的有效方法，从氨基酸或其相应的市售 N-羟基琥珀酰亚胺酯开始，以优异的产率合成氨酰基-pNA 和氨酰基-AMC 衍生物。该方法涉及受保护氨基酸的硒代羧酸中间体的原位形成以及随后与叠氮化物的非亲核酰胺化。氨基酸/肽化学中使用的常见保护基团都具有良好的耐受性。该方法还成功应用于二肽偶联物的合成，表明该方法适用于含有短肽的显色底物的合成。
