Beschreibung

General description

Di-tert-butyl azodicarboxylate is a an acid labile reagent for Mitsunobu reactions allowing facile isolation of products and for the electrophilic amination and hydrazination of enolates and lithium alkyls.

Application

Reactant for:

• Preparation of hexapeptide key fragments via stereoselective selenocyclization/oxidative deselenylation or hydrazination/cyclization reactions
• Asymmetric Michael addition reactions
• Preparation of dipeptidyl peptidase IV dependent water-soluble prodrugs via Mitsunobu reaction
• Synthesis of pyrroloisoquinoline template via stereoselective N-acyliminium-mediated cyclization and enolate amination for synthesis of peptidomimetic compounds
• Barbier-type propargylation reactions
• Synthesis of bacterial peptide deformylase (PDF) inhibitor fumimycin
• Asymmetric amination of glycine Schiff bases
