dicyclohexylcarbodiimide (DCC) as a condensing agent. Several N-blocked α-amino acids have been loaded on this resin by use of DCC. The amino acid resin can be utilized for peptide synthesis. Repetitive usage of the resin in the form of esters and facile synthesis of a biologically active pentapeptide, Leu5-enkephalin, show the usefulness of the polymer-bound 1-hydroxy-2-pyrrolidinone.
使用二环己基碳二亚胺 (DCC) 作为缩合剂,通过氨基甲基化共聚(苯乙烯-2% 二乙烯基苯)与 1-羟基-5-氧代-3-吡咯烷羧酸反应制备了聚合物键环状 N-羟基酰胺。通过使用 DCC,已将几种 N 封闭的 α-氨基酸加载到该树脂上。氨基酸树脂可用于肽合成。以酯的形式重复使用树脂并轻松合成具有生物活性的五肽 Leu5-脑啡肽,显示了聚合物结合的 1-羟基-2-吡咯烷酮的有用性。
