Safety of 4-Hydrazinylbenzenesulfonamide hydrochloride, Career opportunities within science and technology are seeing unprecedented growth across the world, and those who study chemistry or another natural science at university now have increasingly better career prospects. 17852-52-7, Name is 4-Hydrazinylbenzenesulfonamide hydrochloride, SMILES is O=S(C1=CC=C(NN)C=C1)(N)=O.[H]Cl, belongs to phthalazine compound. In a article, author is Yuan, Chunhao, introduce new discover of the category.
The Cu(I)-catalyzed highly enantioselective [3 + 3] cycloaddition between two different 1,3-dipoles, phthalazinium dicyanomethanides and iminoester-derived azomethine ylides, has been achieved under mild reaction conditions, providing novel chiral heterocyclic compounds, 2,3,4,11b-tetrahydro-1H-pyrazino[2,1-a]phthalazine derivatives, in high yields with excellent diastereo- and enantioselectivies (up to 99% yield, 99% ee, >20:1 dr).
