Application

Diethyl azodicarboxylate (DEAD) is a reagent used in the Mitsunobu reaction.
DEAD can also be used as a reagent in the:
  • Synthesis of esters, ethers, amines, and thioethers of alcohols.
  • Oxidation of alcohols to carbonyl derivatives using ZnBr2 as a catalyst via dehydrogenation reaction.
  • Conversion of alcohol to an azide key intermediate in the total synthesis of immunostimulant α-galactosylceramides.
  • Synthesis of aza-β-lactams from aryl(alkyl)ketenes.
  • Synthesis of 1H-1,2,4-triazole-1,4(5H)-dicarboxylate derivatives.
  • Diels-Alder type reactions.

Reactant for preparation of:
  • Immunostimulants α-Galactosylceramides
  • Cellotriose and cellotetraose analogues as transition state mimics for mechanistic studies of cellulases
  • Bisubstrate inhibitors with molecular recognition at the active site of catechol-O-methyltransferase
  • Derivatives of F200 and S383 with cannabinoid CB1 receptor binding activities
  • Aza-β-lactams via NHC-catalyzed [2 + 2] cycloaddition with ketenes

Reagent for:
  • Annulation of N-protected imines
  • α-thiocyanation of enolizable ketones with ammonium thiocyanate
  • Diels-Alder reactions
