Pyrrolidine-2,4-diones have been identified as a novel starting point for the synthesis of peptide analogues. This paper describes a method for the efficient and diastereoselective incorporation of this moiety into peptide chains to furnish di- and tripeptide analogs. The stability of these pyrrolidinone modified di- and tripeptides was found to be markedly improved when compared to that of a natural peptide. In addition, solid phase peptide synthesis employing a pyrrolidinone containing tripeptide is demonstrated.
吡咯烷-2,4-二酮已被确定为合成肽类似物的新起点。本文介绍了一种高效、非对映选择性地将吡咯烷-2,4-二酮掺入肽链以合成二肽和三肽类似物的方法。与天然肽相比,这些经吡咯烷酮修饰的二肽和三肽的稳定性明显提高。此外,还展示了利用含有吡咯烷酮的三肽进行固相肽合成的方法。
