Application
Employed in a palladium-catalyzed cross-coupling with vinyl halides leading to N-Boc-N-alkenylhydrazines.
Reagent used in solid phase peptide synthesis and in α-amino aldehyde optical purity determinations. Condenses with aldehydes to form hydrazones which are intermediates in the synthesis of HIV-1 protease inhibitors.

N-Boc-N-alkenylhydrazines, an almost unknown type of compounds, have been prepared with high to moderate yields via palladium-catalyzed cross-coupling between alkenyl halides and tert-butyl carbazate. The present methodology represents the first general way to access this highly functionalized and unusual type

Steroids are the standard therapy for autoimmune hepatitis (AIH) but the long-lasting administration is hampered by severe side effects. Methods to improve the tropism of the drug toward the liver are therefore required. Among them, conjugation to nanoparticles represents one
