Pd(ii)-Catalyzed regioselective functionalization of antipyrines: synthesis of pyrazolono-maleimides and pyrazolono-quinones?
Organic & Biomolecular Chemistry Pub Date: 2021-05-14 DOI: 10.1039/D1OB00819F
Abstract
A Pd(II)-catalyzed direct functionalization reaction of the 4Csp2–H bond of antipyrine derivatives is reported. This metal-catalyzed reaction of antipyrines with maleimides provided an easy and efficient access to biologically important pyrazolonomaleimides. This catalytic system is also applicable for C-4 functionalization of the antipyrine ring with quinone derivatives.
