In view of developing alternatives to classical peptide synthesis strategies that suffer from low efficacy and negative environmental impact, the reactivity of N-protected α-amino acids, amino esters, and N-ethyl-N′-(3-dimethylaminopropyl)carbodiimide was studied under liquid-assisted grinding (LAG) conditions. The optimal reaction conditions enabled the intensive and environmentally benign mechanosynthesis
鉴于开发效率低且对环境产生负面影响的经典肽合成策略的替代方案,研究了 N-保护的 α-氨基酸、氨基酯和 N-乙基-N'-(3-二甲氨基丙基)碳二亚胺的反应性在液体辅助研磨 (LAG) 条件下。最佳反应条件能够实现多种二肽的密集且环境友好的机械合成,这些二肽可以生产至数克规模。揭示了液体添加剂的性质对反应过程的关键影响。结合无溶剂叔丁氧羰基脱保护步骤,这种方法被应用于三肽和四肽的合成,从而为合成更长的肽开辟了道路。
