The dual native chemical ligation at lysine strategy was revised by replacing the acid-labile Cbz protecting group with photolabile NVOC at the 4-mercaptolysine side chain. The optimized strategy was subsequently applied to the synthesis of K48-linked diubiquitin.
通过在4巯基赖氨酸侧链上用光不稳定的NVOC取代对酸不稳定的Cbz保护基,修订了在赖氨酸策略上的双重天然化学连接。随后将优化的策略应用于K48连接的双泛素的合成。
