Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 56413-95-7, is researched, SMILESS is N#CC1=NC(Cl)=C(Cl)N=C1C#N, Molecular C6Cl2N4Journal, Tetrahedron Letters called Highly efficient synthesis of 5,6-disubstituted-5H-pyrrolo[2,3-b]pyrazine-2,3-dicarbonitriles through a one-pot palladium-catalyzed coupling reaction/cyclization in water, Author is Keivanloo, Ali; Bakherad, Mohammad; Nasr-Isfahani, Hossein; Esmaily, Somayeh, the main research direction is amino chloropyrazine dicarbonitrile preparation phenylacetylene palladium copper SDS heterocyclization; pyrrolopyrazine dicarbonitrile preparation; heterocyclization catalyst palladium copper SDS.HPLC of Formula: 56413-95-7.
A highly efficient one-pot synthesis of 5,6-disubstituted-5H-pyrrolo[2,3-b]pyrazine-2,3-dicarbonitriles is presented. The reaction of 5-(alkyl/arylamino)-6-chloropyrazine-2,3-dicarbonitriles with phenylacetylene, catalyzed by Pd-Cu, in the presence of SDS as the surfactant in water, leads to the desired products in good-to-high yields.
Here is just a brief introduction to this compound(56413-95-7)HPLC of Formula: 56413-95-7, more information about the compound(5,6-Dichloropyrazine-2,3-dicarbonitrile) is in the article, you can click the link below.
