carbonylating agent for coupling the properly substituted hydrazide to the proline nitrogen to obtain the AzAsx-Pro or AzAla-Pro aza-sequence (Az denotes the replacement, and Asx stands for Asn or Asp). The structure of three Z-AzAsx-Pro-NHiPr and of the Boc-AzAla-Pro-NHiPr aza dipeptides has been studied in solution by 1H-NMR and IR spectroscopy, and three of them have been investigated in the crystalline state
肽中的一种可能的α-修饰是用氮取代CαH基团。我们建议使用三光气作为羰基化剂,以将适当取代的酰肼偶联至脯氨酸氮上,从而获得AzAsx-Pro或AzAla-Pro氮杂序列(Az表示取代,而Asx代表Asn或Asp)。通过1 H-NMR和IR光谱研究了三种Z-AzAsx-Pro-NH i Pr和Boc-AzAla-Pro-NH i Pr氮杂二肽的结构,并在其中研究了其中的三种。通过X射线衍射得到结晶态。
