A new and unprecedented exploitation of quinolinium thioester salts 2 in peptide bond formation is reported. These synthetic tools were assessed during the preparation of a number of dipeptides 3a-f obtained in good yields with complete stereochemical integrity. A sequential mechanism related to a prior amine capture strategy is well-established. Additionally, a tripeptide 3g was prepared according
报道了喹啉硫酯盐 2 在肽键形成中的新的和前所未有的开发。这些合成工具在制备大量二肽 3a-f 的过程中进行了评估,这些二肽以良好的收率获得,具有完全立体化学完整性。与先前的胺捕获策略相关的顺序机制是公认的。此外,根据“安全捕获”方法制备了三肽 3g,从而证明了这些新合成工具在设计可用于固相肽合成 (SPPS) 的新安全捕获连接器方面的重要潜力。
