with a range of unprotected side chains of aminoacid. The ability to produce amide or peptides by a traceless removal of the auxiliary is a significant virtue of the method. Meanwhile, the application of this new peptide-bond-forming reaction to the synthesis of novel endomorphin (EM) derivatives with various binding potencies was realized.
An Efficient Synthesis of Nα-Protected Amino and Peptide Acid Aryl Amides via Iodine-Mediated Oxidative Acylation of Nα-Protected Amino and Peptide Thioacids
Abstract Thioacids derived from N-protected amino or dipeptide and tripeptide acids undergo facile N-acylation with aromatic amines to afford N-protected amino or peptide aryl amides in good to excellent yields and enantiopurities. The method also furnishes difficult-to-prepare N-Fmoc amino acid 4-nitroanilides in good yields. This simple oxidative Nα-acylation of thioacids with aromatic amines proceeds
