  Sustainable and efficient manufacturing methods for N-methylated peptides remain underexplored despite growing interest in therapeutic N-methylated peptides within the pharmaceutical industry. A methodology for the coupling of C-terminally unprotected N-methylamino acids mediated by an isostearic acid halide (ISTAX) and silylating reagent has been developed. This approach allows for the coupling of

  尽管制药行业对治疗性N-甲基化肽的兴趣日益浓厚，但N-甲基化肽的可持续和高效制造方法仍未得到充分探索。已经开发了一种由异硬脂酰卤 (ISTAX) 和甲硅烷基化试剂介导的C-末端未保护N-甲基氨基酸的偶联方法。这种方法允许在温和条件下以高产率偶联多种氨基酸和肽，而无需在C的过程中进行C端脱保护步骤-末端伸长。这些优点使其成为生产含有N-甲基氨基酸的肽治疗剂和诊断剂的有用合成方法。

  The O-acyl isopeptide method has recently received attention as an efficient synthetic method for peptides. Herein, forty kinds of "O-acyl isodipeptide unit" Boc-Ser/Thr(Fmoc-Xaa)-OH (1-40) were effectively synthesized in two-steps without epimerization. The O-acyl isodipeptide units are important building blocks to enable the routine use of the O-acyl isopeptide method.

  unusual residues significantly heightened the synthetic challenges, impeding the solid-phase peptide synthesis (SPPS) of 1. In this study, we first addressed the synthesis problem by extensive optimization of various factors of the SPPS. Adaptation of a new protective group strategy allowed for elongation of a 37-mer peptide on resin, to which an N-terminal 11-mer fragment was condensed. Removal of the
