We are grateful to our colleagues C. Fehér, S. Heald, P. Schmitt, and S. Seip for NMR analyses. G. Schiffer determined the minimal inhibitory concentrations. A. Mayer-Bartschmidt and M.-A. Brüning carried out the fermentations. W. Schröder helped us with small-scale peptide analyses. J. Ragot resynthesized compound 2. We thank A. Göller, J. Schamberger, and M. Lobell for fruitful discussions about the 3D structure. We are indebted to H. Wild and H. Haning for their continuous support of this project and to H. Schirok and N. Griebenow for a critical revision of the manuscript.

Graphical Abstract

Tackle-resistant bacteria: Determination of the 3D structure of the antibiotic lysobactin has led to its total synthesis and resulted in a high-yielding macrolactamization step. The minimal use of protecting groups allowed preorganization of the side chains to steer the cyclization. Thus, a new chemical route has been developed in the search for innovative antibiotic lead structures.
