The invention relates to the use of chelating polymers with affinity for group-Ill cations, preferably poly-hydroxamic acid or poly-iminodiacetic acid, in the manufacturing of a medicament for the treatment of inflammatory bowel disease (IBD).
n-Bu4NI/H2O2-catalyzed mild conversion of hydroxamic acids to carboxylic acids
A variety of aromatic and aliphatic hydroxamic acids were transformed into carboxylic acids employing tetra-n-butylammonium iodide and hydrogen peroxide. The reaction was executed across a range of substrates encompassing diverse functional groups, delivering good to excellent yields. This catalytic hydrolysis features gentle reaction conditions and the application of a non-hazardous, cleanly processed
