Benzene is an important organic compound with the chemical formula C6H6, and its molecule consists of a ring of 6 carbon atoms, each with 1 hydrogen atom. Benzene is a sweet, flammable, colorless and transparent liquid with carcinogenic toxicity at room temperature, and has a strong aromatic odor. It is insoluble in water, easily soluble in organic solvents, and can also be used as an organic solvent itself. The ring system of benzene is called benzene ring, and the structure after removing one hydrogen atom from the benzene ring is called phenyl. Benzene is one of the most important basic organic chemical raw materials. Many important chemical intermediates can be derived from benzene through substitution reaction, addition reaction and benzene ring cleavage reaction.
Imidazolines are a class of heterocycles derived from imidazoles by reduction of one of the two double bonds. Three isomers are known, 2-imidazoline, 3-imidazoline and 4-imidazoline. 2 and 3-imidazolines contain imine centers, while 4-imidazolines contain alkene groups. The 2-imidazoline group occurs in several drugs. Imidazolines are an important class of compounds found in many natural and medicinal products. These compounds are also used as intermediates in the synthesis of organic molecules. Furthermore, chiral imidazolines are widely used as organic catalysts for the synthesis of various natural and synthetic organic compounds.
Imidazole is an important five-membered nitrogen-containing heterocyclic compound. Among the numerous heterocyclic compounds, imidazole and its derivatives are regarded as a unique and multifaceted scaffold material due to their diverse applications in industrial, organic and pharmaceutical chemistry. Imidazoles interact in different ways with many therapeutic targets, enzymes and receptors in biological systems and thus exhibit a wide range of biological activities. In particular, several imidazoles can be used as clinical drugs to treat various types of cancer with high therapeutic efficacy. Furthermore, imidazoles are one of the most critical segments in the field of anti-covid-19 virus drug discovery due to their ability to interact with active targets in living systems.
