Synthesis and structure confirmation of fuscachelins A and B, structurally unique natural product siderophores from Thermobifida fusca

Abstract

The fuscachelin siderophores have been prepared synthetically as have their metal chelation complexes. The heterodimeric nature of the fuscachelin decamer lends itself to a convergent synthetic strategy. Synthetic access to the natural products and intermediates will provide readily adaptable tools in future studies examining iron-sequestration and the biosynthetic machinery.
