DIFORMYLIMIDE SODIUM SALT

Slightly beige powder

Reactant for preparation of:

• Functionalized condensed benzazoles
• α-ketoheterocycles as inhibitors of Leishmania mexicana cysteine protease CPB
• INOS inhibitor PHA-399733 via Bucherer-Bergs hydantoin synthesis
• Antibiotic resistance (C β-lactamase AmpC ) inhibitor analogues, with improved cell permeability properties
• BINOL- and H8-BINOL-based aryl phosphites as ligands in palladium-catalyzed asymmetric allylation and amination reactions
• Precursors of αVβ3 integrin antagonists

Grind the amide under dry tetrahydrofuran (fumehood), filter and wash it with this solvent, then dry it in vacuo. It is soluble in EtOH and H2O but insoluble in Et2O and pet ether.
