And the article was included in Mendeleev Communications in 2021.Electric Literature of C9H9N3 This article mentions the following:
7-Nitro-2,3-dihydroimidazo[1,2-a]benzimidazole and its N9-substituted derivatives could be conveniently synthesized by nitration of the corresponding tricyclic precursors with a nitrating mixture or with the HNO3/CF3COOH system. This reaction occurred fairly smoothly and with good regioselectivity. In the experiment, the researchers used many compounds, for example, 2,3-Dihydro-1H-benzo[d]imidazo[1,2-a]imidazole (cas: 24134-26-7Electric Literature of C9H9N3).
2,3-Dihydro-1H-benzo[d]imidazo[1,2-a]imidazole (cas: 24134-26-7) belongs to imidazole derivatives. Among the different heterocyclic compounds, imidazole is better known due to its broad range of chemical and biological properties. Imidazole has become an important synthon in the development of new drugs. The pharmacophore of imidazole exists in bioactive compounds including amino acids, plant growth regulators and therapeutic agents.n increase of the alkyl chain length of the alcohols.
