Abstract

A general, mild and efficient procedure with which to access hydroxamic acids, in good yields and purity, is reported. Esters are used as substrates and reacted with hydroxylamine, in the presence of a base, under microwave activation. The method has been successfully applied to enantiomerically pure esters without loss of stereochemical integrity.
