(S)-α-Amino-δ-nitropentanoic acid (δ-nitro-L-norvaline), an intermediate of the total synthesis of ferrichrome, was synthesized starting from diethyl oxalate and γ-butyrolactone.
The elusive structure of malleobactin, a virulence factor of pathogens belonging to the Burkholderia mallei family, was finally unveiled by genetic and chemical analyses. The novel nitro‐substituted siderophore is derived from an unusual, unprotected hydroxylamine, which undergoes spontaneous oxidation, as shown by in vitro assays and detection of analogues featuring hydroxylamino, nitroso, and azoxide
