• W3136751943 abstract "Abstract Benzimidazole is an important heterocycle that is widely researched and utilized by the pharmaceutical industry and is one of the five most commonly used five-membered aromatic heterocyclic compounds approved by the US Food and Drug Administration. In view of their wide-ranging bioactivities, systems containing benzimidazole as one of the moieties occupy a special place among other benzimidazole derivatives. Since 2010, many improved synthetic strategies have been developed for the construction of hetaryl- and arylbenzimidazole molecular scaffolds under environmentally benign conditions. This review emphasizes the recent trends and modifications frequently used in the synthesis of derivatives of benzimidazole such as the Phillips–Ladenburg and Weidenhagen reactions, as well as entirely new methods of synthesis, involving oxidative cyclization, cross-coupling, ring distortion strategy, and rearrangements carried out under environmentally benign conditions. 1 Introduction 2 From 1,2-Diaminobenzenes with Various One-Carbon Unit Suppliers 2.1 Phillips–Ladenburg Reaction 2.1.1 With (Het)arenecarboxylic Acids 2.2.2 With (Het)arenecarboxylic Acid Derivatives 2.2 Weidenhagen Reaction 2.2.1 With (Het)arenecarbaldehydes or (Het)aryl Methyl Ketones 2.2.2 With Primary Alcohols 2.2.3 With Primary Alkylamines 2.2.4 With 2-Methylazaarenes 2.2.5 With Other One-Carbon Fragment Suppliers 3 From 2-Haloacetanilides and Amines 4 From Amidines 5 From Tetrahydroquinazolines 6 Mamedov Rearrangement 7 Conclusions and Outlook" @default.
