Di-tert-butyl azodicarboxylate is a reagent used in the preparation of acyl hydrazinedicarboxylates. It is also used in the electrophilic amination of beta-keto esters catalyzed by an axially chiral guanidine. It serves as a precursor in an enantioselective synthesis of 3,6-dihyropyridazines employing organocatalysts such as L-proline or (S)-2-pyrrolidinyl tetrazole. It is also utilized in the asymmetric Friedel-Crafts amination through a chiral organocatalyst. Further, it acts as a reactant for preparation of hexapeptide key fragments through stereo selective selenocyclization/oxidative deselenylation reactions. In addition to this, it is employed as a starting material in the synthesis of pyrroloisoquinoline template through stereoselective N-acyliminium-mediated cyclization and enolate amination for preparation of peptidomimetic compounds and Barbier-type propargylation reactions.


Light sensitive. Store in a cool place. Keep the container tightly closed in a dry and well-ventilated place. Incompatible with strong bases and alcohols.
