Pyrido[2,3-b]pyrazine (cas: 322-46-3) belongs to pyrazine derivatives. Pyrazine is an N-heterocyclic moiety, and it can be easily prepared from ethylenediamine and 1,2-diketone, α-hydroxyketone, α-methyl ketone. Pyrazine heterocycles and their benzo derivatives possess many interesting properties, including chemical reactivity profiles, and have diverse applications in total synthesis, medicine, chemical biology, materials, dyes, and imaging.Synthetic Route of C7H5N3

Pyridopyrazines was written by Zhang, J.. And the article was included in Science of Synthesis, Knowledge Updates in 2010.Synthetic Route of C7H5N3 This article mentions the following:

This manuscript is an update of the original Science of Synthesis chapter and includes methods for the preparation of pyrido[2,3-b]pyrazine derivatives and pyrido[3,4-b]pyrazine derivatives described in the literature up to 2010. Methods proceeding by a condensation of pyridinediamine derivatives with carbonyl compounds and the application of (halo)pyrido[2,3-b]pyrazines by palladium-catalyzed cross-coupling reactions are covered. In the experiment, the researchers used many compounds, for example, Pyrido[2,3-b]pyrazine (cas: 322-46-3Synthetic Route of C7H5N3).
