Inexpensive Radical Methylation and Related Alkylations of Heteroarenes was written by Huang, Qi;Zard, Samir Z.. And the article was included in Organic Letters in 2018.Synthetic Route of C4H5N3O2 This article mentions the following:
A simple method for the introduction of a Me and higher aliphatic group to various heteroarenes using very inexpensive reagents is described. It is based on the radical addition of a carboxylic xanthate followed by decarboxylation. Depending on the heteroarene structure, the decarboxylation can be spontaneous or induced by heating in N,N-dimethylacetamide or N-Me pyrrolidone in a microwave oven. In the experiment, the researchers used many compounds, for example, 1-Methyl-4-nitroimidazole (cas: 3034-41-1Synthetic Route of C4H5N3O2).
1-Methyl-4-nitroimidazole (cas: 3034-41-1) belongs to imidazole derivatives. Many natural products, especially alkaloids, contain the imidazole ring. These imidazoles share the 1,3-C3N2 ring but feature varied substituents. Imidazole is incorporated into many important biological compounds. The most pervasive is the amino acid histidine, which has an imidazole side-chain. Histidine is present in many proteins and enzymes, e.g. by binding metal cofactors, as seen in hemoglobin.Synthetic Route of C4H5N3O2
