The development of a novel fluorene-type anchor support molecule and a liquid-phase peptide synthesis protocol (AJIPHASE®) is reported. With this support molecule, the synthesis of a protected peptide with a free carboxyl group could be carried out by repeated coupling/deprotection reactions and isolation by simple precipitation. Cleavage is performed under mild acidic conditions (2% TFA/CHCl3 or
据报道,新型芴型锚定支持分子和液相肽合成方案(AJIPHASE®)的开发。利用该支持分子,可以通过重复的偶联/去保护反应和通过简单的沉淀分离来合成具有游离羧基的被保护的肽。在温和的酸性条件(2%TFA / CHCl 3或六氟异丙醇)下进行裂解,以高收率和高纯度释放出产物。没有发现二酮哌嗪的形成或侧链保护基被去除的迹象。
