strategy in solid phase peptide synthesis was developed using a new safety-catch type of semi-permanent protecting groups and new linkers which were derived from 4-methylsulfinylbenzyl protection. This new strategy was based on a two-dimensional protection scheme employing acid-labile temporary and acid-stable but reductive acidolysis-cleavable semi-permanent protecting groups. By using this strategy
使用新型安全捕捉类型的半永久性保护基和衍生自4-甲基亚磺酰基苄基保护的新连接基,开发了固相肽合成中的还原性酸解最终脱保护策略。该新策略是基于二维保护方案的,该方案采用酸不稳定的临时酸和酸稳定但可还原的酸解可裂解的半永久性保护基。通过使用这种策略,我们成功地合成了四个模型肽,其中两个包含C末端酰胺。
