Fier, Patrick S.; Kim, Suhong; Cohen, Ryan D. published an article about the compound: 5,6-Dichloropyrazine-2,3-dicarbonitrile( cas:56413-95-7,SMILESS:N#CC1=NC(Cl)=C(Cl)N=C1C#N ).Category: chiral-oxygen-ligands. Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:56413-95-7) through the article.
The development of a multifunctional reagent for the direct conversion of pyridines to Boc-protected 2-aminopyridines such as I [R = H, 3-Br, 4-Ph, etc.] with exquisite site selectivity and chemoselectivity was reported. The novel reagent was prepared on 200g scale in a single step, reacted in title reaction under mild conditions without precautions toward air or moisture, and is tolerant of nearly all common functionality. Exptl. and in situ spectroscopic monitoring techniques provided detailed insights and unexpected findings for the unique reaction mechanism.
There is still a lot of research devoted to this compound(SMILES：N#CC1=NC(Cl)=C(Cl)N=C1C#N)Category: chiral-oxygen-ligands, and with the development of science, more effects of this compound(56413-95-7) can be discovered.
