3,4-Dimethylpyrrolo[1,2-a]pyrazine

Description

3,4-Dimethylpyrrolo[1,2-a]pyrazine belongs to the class of organic compounds known as pyrrolopyrazines. Pyrrolopyrazines are compounds containing a pyrrolopyrazine moiety, which consists of a pyrrole ring fused to a pyrazine. Pyrrole is 5-membered ring consisting of four carbon atoms and one nitrogen atom. Pyrazine is a 6-membered ring consisting of six carbon atoms and two nitrogen centers at ring positions 1 and 4. Based on a literature review very few articles have been published on 3,4-Dimethylpyrrolo[1,2-a]pyrazine.
