Benzimidazole is a heterocyclic compound formed by fusing the benzene ring with an imidazole ring that contains two nitrogen atoms. Benzimidazole and its derivatives are prepared in different ways, including condensation of o-phenylenediamine with carbonyl compounds (aldehydes and ketones) or with carboxylic acids and their derivatives. The benzimidazoles can also be prepared by rearranging other heterocyclic compounds such as quinoxaline derivatives, triazole derivatives, etc. In recent decades, benzimidazoles were prepared using green methods such as microwaves, ultrasound, and the use of an environmentally friendly catalyst, as well as photochemical reactions. Benzimidazoles have attracted the interest of scientists and researchers due to the great medical efficacy shown by them for various diseases. The benzimidazole derivatives show many pharmacological activities such as anticancer, anti-inflammatory, antioxidant, anticoagulant, antiviral, etc. This review focuses on shedding light on benzimidazole and its derivatives, the most important methods used to prepare it, as well as the biological applications in our daily lives.

“…On the other hand, the synthetic aspect of quinazolinone and its derivatives carried out by condensation reaction of isatoic anhydride, primary amine, or ammonium salts with aldehydes was widely employed. It was catalyzed by β-cyclodextrin-SO 3 H [12], nanoparticles [13,14], Saccharomyces cerevisiae (baker's yeast) [15], Montmorillonite K10 [16], cation-exchange resin [17], palladium [18], ionic liquid-water [19], and so on. A vast number of quinazolinone derivatives have been designed to provide effective drugs, especially some antifungal agents such as tryptanthrin [20,21] and 2acetylquinazolin-4(3H)-one [22,23].…”

Three new series of quinazolinone derivatives containing amide, urea, and sulfonamide were synthesized through multistep synthesis. The required intermediates 4‐[(4′‐oxo‐2,3,3′,4′,5,6‐hexahydro‐1′H‐spiro[pyran‐4,2′‐quinazolin]‐1′‐yl)methyl]benzoic acid 4 and 1′‐(3‐aminobenzyl)‐2,3,5,6‐tetrahydro‐1′H‐spiro[pyran‐4,2′‐quinazolin]‐4′(3′H)‐one 8 were prepared by hydrolysis of ester and reduction of nitro intermediates. Three different series of compounds were synthesized from these two scaffolds. The key scaffolds 4 and 8 were successfully converted to target molecules via amides 5a–k, urea 9a–f, and substituted sulfonamides 10a–e. The chemical structures of newly synthesized compounds were characterized by spectral analysis. The structure of 5d was confirmed by X‐ray crystallography study. These newly synthesized compounds were screened for antibacterial studies against Staphylococcus epidermidis, Salmonella typhi, Proteus mirabilis, and Shigella sonnei and for the antifungal activity against Aspergillus niger and Candida albicans. Among all the compounds, 9b–d showed excellent activities against S. typhi. Compound 9a showed moderate activity against all fungi stains, and 5I showed moderate activity against P. mirabilis, while the other derivatives showed fairly good activities.
