promising method for the high-throughput synthesis of linear C-hydroxyalkylamido peptidomimetics and β-turn cyclic peptidomimetics via “volatilizable” aminoalkyl functionalized silica gels is presented. Boc amino acids and carboxylic acids were coupled on functionalized aminoalkyl silica gels using a standard DIC/HOBt coupling protocol. After peptide synthesis, the resin bound peptide was cleaved using
提出了一种通过“可挥发”氨基烷基官能化硅胶高通量合成线性C-羟烷基酰胺肽模拟物和 β-转角环状肽模拟物的有前途的方法。Boc 氨基酸和羧酸使用标准 DIC/HOBt 偶联方案在功能化氨基烷基硅胶上偶联。肽合成后,使用两步法切割树脂结合的肽以获得线性C-羟烷基酰胺肽模拟物。β-Turn 环状肽模拟物是通过分子内 S N Ar 环化在水溶液中产生的。通过“一锅”反应,线性和环状肽模拟物均以良好至极好的产率和纯度获得。
