A simple and efficient method for the synthesis of O-acylhydroxamate derivatives from oxime chlorides and carboxylic acids was developed. The reaction affords clean and facile access to diverse O-acylhydroxamates in high yields (up to 85%). The chemical structure of a typical product was confirmed using single-crystal X-ray structure analysis.

Selective O-benzoylation of hydroxamic acids is achieved by the treatment of BPO and DABCO. Aliphaticalcohols are not reactive under these conditions. Various radical or oxidation sensitive functional groups are compatible with this protocol, and no anhydrous reagents or solvents are required for the high yields of the benzoylations.

Rapid, quantitative and regioselective O-acylation/O-benzoylation of hydroxamic acids has been carried using polymer supported hydroxamate anions and acetyl/benzoyl chloride under mild conditions. The isolation of unambiguous and pure products by simple work-up is also an important feature of this method.
