O-Acyl isodipeptides are prepared by coupling Boc-Ser/Thr-OBzl with Fmoc-Xaa-OH employing COMU, well
known third generation peptide coupling agent. The reaction proceeds with high yield and the chemical homogeneity of
the synthesized molecules were established via chiral HPLC analyses. The O-acyl isodipeptide units play crucial role in
the success of ‘click peptide’ protocol employed for assembling ‘difficult sequence’ peptides.
O-酰基异二肽通过使用第三代肽
偶联剂COMU,将Boc-Ser/Thr-OBzl与Fmoc-Xaa-OH偶联制备而成。该反应具有高产率,合成分子的
化学均一性通过手性HPLC分析确定。O-酰基异二肽单元在用于组装“困难序列”肽的“点击肽”方案中发挥关键作用。
