    • The invention relates to a method for homogeneous solution phase peptide synthesis (HSPPS) of a N-terminal peptide fragment PEP-N and a C-terminal peptide fragment C-PEP, with C-PEP carrying a specific diketopiperazine (DKP) comprising C-terminal protecting group, which contains a handle group HG, with HG being connected to the C-terminus of the peptide fragment; thereby this specific DKP comprising C-terminal protecting group can be selectively cleaved from the peptide as a conventionally used C-terminal protecting group. By the use of this DKP and HG comprising C-terminal protecting group, certain process steps in convergent peptide synthesis based on a combination of HSPPS and solid phase peptide synthesis (SPPS) can be avoided. The invention relates further to a method for the preparation of such specifically protected fragment C-PEP by SPPS by using a linker comprising a specific dipeptide and HG for connecting the growing peptide chain to the resin, which linker forms said DKP group, when the peptide fragment C-PEP is cleaved from the supporting resin; and further to the intermediates of the preparation method.
    • 本发明涉及一种N-末端肽片段PEP-N和C-末端肽片段C-PEP的均相溶液相肽合成(HSPPS)的方法,其中携带特异性二酮哌嗪(DKP)的C-PEP包含C- 末端保护基,其含有句柄组HG,其中HG连接到肽片段的C末端; 因此,作为常规使用的C末端保护基可以从肽中选择性地切割含有C末端保护基的这种特定的DKP。 通过使用包含C末端保护基的该DKP和HG,可以避免基于HSPPS和固相肽合成(SPPS)的组合的收敛肽合成中的某些方法步骤。 本发明进一步涉及通过使用包含特异性二肽和HG的连接体将这种特异性保护的片段C-PEP制备成用于将生长中的肽链连接到树脂上的方法,该连接体形成所述DKP基团,当肽 片段C-PEP与支撑树脂分离; 并且还涉及制备方法的中间体。
