The total synthesis of a novel siderophore, acinetoferrin, is described. The key transformation involves the tandem oxidation and acylation of the N3-amino group of N1-BOC propane diamine prior to coupling with the external carboxyls of citric acid. A 'one-pot-two-step' reaction converted a primary amine (RNH2) into a O-benzoyl hydroxamate (i.e., RN(OOCPh)COR') in good yield (68%). These studies demonstrated the utility of the O-benzoyl protecting group in the synthesis of α,β-unsaturated hydroxamic acids.
Synthesis of secondary amines via N-(benzoyloxy)amines and organoboranes

A variety of primary amines (R-NH2) were converted to their corresponding N-(benzoyloxy)amines (i.e., R-NHOCOPh) under biphasic conditions in excellent yields (63-90%). The intermediate N- (benzoyloxy)amines were converted to their N-ethylamine derivatives upon reaction with triethylborane in THF in good yield (54-89%). These experiments demonstrated the similar chemistry of N-chloro- and N-(benzoyloxy)amines with organoboranes.
