Total synthesis of the bismacrocyclic thiopeptide antibiotic nosiheptide was achieved through the assembly of a fully functionalized linear precursor followed by consecutive macrocyclizations. Key features are a critical macrothiolactonization and a mild deprotection strategy for the 3‐hydroxypyridine core. The natural product was identical to isolated authentic material in terms of spectral data and antibiotic activity.
