General description

Di-tert-butyl hydrazodiformate acts as hydrazine substrate during the preparation of protected pyridylhydrazine derivatives.

Application

Di-tert-butyl hydrazodiformate was used as starting reagent during the four-step synthesis of the aminobicyclopyrazolone hydrochloride. It was used as reagent during Pd-catalyzed amination reactions of halo-pyridine substrates.

[reaction in text] Protected pyridylhydrazine derivatives were prepared in a one-step palladium-catalyzed amination reaction using chelating phosphine ligands. 2-Pyridyl chlorides, bromides, and triflates were effective electrophiles in these reactions. Di-tert-butyl hydrazodiformate was an excellent hydrazine substrate, and the resulting products

The development of (99m)Tc-estradiol radiopharmaceuticals would be advantageous for the detection of estrogen receptor-positive breast tumors. Estradiol derivatives conjugated to organometallic tricarbonyl-Tc(I) and related Re(I) complexes are capable of achieving high receptor binding affinity, but effective methods for synthesizing radiolabeled

BCL-2 family proteins converge at the mitochondrial outer membrane to regulate apoptosis and maintain the critical balance between cellular life and death. This physiologic process is essential to organism homeostasis and relies on protein-protein and protein-lipid interactions among BCL-2 family
