Total Synthesis of Mannopeptimycin β via β-Hydroxyenduracididine Ligation

J Am Chem Soc. 2021 Aug 18;143(32):12784-12790. doi: 10.1021/jacs.1c05922. Epub 2021 Aug 5.

Abstract

Nonribosomal peptide synthesis in bacteria has endowed cyclic peptides with fascinating structural complexity via incorporating nonproteinogenic amino acids. These bioactive cyclic peptides provide interesting structural motifs for exploring total synthesis and medicinal chemistry studies. Cyclic glycopeptide mannopeptimycins exhibit antibacterial activity against antibiotic-resistant Gram-positive pathogens and act as the lipid II binder to stop bacterial cell wall biosynthesis. Here, we report a strategy streamlining solution phase-solid phase synthesis and chemical ligation-mediated peptide cyclization for the total synthesis of mannopeptimycin β.
