Descripción

Aplicación

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
