2-dimethyl-2H-azirin-3-yl)-L-prolinate are reported. Reactions of these 2H-azirin-3-amine derivatives with Z-protected amino acids have shown them to be suitable synthons for the Aib-Pro unit in peptide synthesis. After incorporation into the peptide by means of the ‘azirine/oxazolone method’, the C-termini of the resulting peptides were deprotected selectively with Zn in AcOH or by a mild Pd0-promoted procedure, respectively
的苯甲酰甲基的合成ñ - (2,2-二甲基-2- ħ -azirin -3-基)-L-脯氨酸和烯丙基ñ - (2,2-二甲基-2- ħ -azirin -3-基)-L-脯氨酸被报道。这些2 H -azirin-3-胺衍生物与Z保护的氨基酸的反应表明,它们是肽合成中Aib-Pro单元的合适合成子。在通过“叠氮基/恶唑酮法”掺入肽后,将所得肽的C末端分别用Zn在AcOH中或通过温和的Pd 0促进的方法选择性地脱保护。
