A new amide-forming ligation that requires a glycine or a primary amine at the linkage site is described herein. The distinguishing feature of this ligation is its reliance on an O-hydroxymethyl salicylaldehyde ester at the C-terminus which allows, via an N,O-acetal intermediate, the formation of a native peptide bond.
本文描述了在连接位点需要甘氨酸或伯胺的新的酰胺形成连接。这种连接的显着特征是它依赖于在C-末端的O-羟甲基水杨醛酯,它允许通过N,O-乙缩醛中间体形成天然的肽键。
