A fundamentally simple, mild, and practical procedure for peptide bond formation is reported that employs a stoichiometric amount of easy‐to‐access 9‐silafluorenyl dichlorides as the coupling agent. Without initial preactivation or elaboration of the carboxylic acid or amine termini of the amino acids, the developed reagent is proposed to act through an unprecedented chemical ligation mechanism, bringing
据报道,一种基本简单,温和且实用的肽键形成方法是采用化学计量的易于获得的9-二氟芴基二氯化物作为偶联剂。无需对氨基酸的羧酸或胺末端进行初步的预活化或精加工,就可以开发出一种通过空前的化学连接机制发挥作用的试剂,从而将两个偶联配偶体聚集在一起,然后再将其消除。因此以高收率和低至无差向异构化提供所需的酰胺或肽键。
