Inflammatory bowel diseases (IBM), such as Crohn's disease, and their common complications represent a global health challenge. Many pyrazole derivatives, such as the spasmolytic drug metamizole, have already found their place among the frequently used th

A concise strategy for the synthesis of substituted 4-acylpyrazole derivatives from N-propargylic sulfonylhydrazones and diaryliodonium salts has been developed. The pyrazole derivatives are formed through a five-step cascade sequence that includes intramolecular cyclization, hydroxylation, elimination, copper-catalyzed aerobic oxidation, and intramolecular rearrangement.
