An Efficient Synthesis of Tri- and Tetrasubstituted Imidazoles from Benzils Using Functionalized Chitosan as Biodegradable Solid Acid Catalyst

An environmentally benign, highly efficient one-pot four-component synthesis of highly functionalized imidazole derivatives using different aldehydes, substituted amines, benzil, and ammonium acetate in the presence of biodegradable and highly efficient catalyst chitosan-SO3H were described. Chitosan-SO3H was found to be a heterogeneous acidic catalyst which allowed easy recovery of the catalyst. Use of microwave irradiation along with chitosan-SO3H for the synthesis of imidazole derivatives makes this protocol green. Moreover, excellent yields, shorter reaction time, chromatography-free purification, and elimination of environmentally hazardous solvents are other advantages of this protocol which leads to sustainability.

The first example of a diastereoselective thio-Ugi reaction: A new synthetic approach to chiral imidazole derivatives

The first example of a diastereoselective thio-Ugi reaction with chiral a-methylbenzylamine is described. The reaction results in formation of two diastereomers of thioamides, the major of which was isolated. We have found that under similar conditions stereochemical results of the thio-Ugi reaction are opposite to stereochemical results of the Ugi reaction. Several chiral thioamides were synthesized. The reaction of thioamides with ammonia results in substituted amidines, which can be cyclized to imidazole derivatives in aqueous HC1. The synthesis of chiral imidazole derivatives was elaborated. Using certain approaches, both isomers of a key synthon in the synthesis of SB203386 (an orally bioactive HIV-1 protease inhibitor) were prepared. The scope, limitations, and stereochemistry of the approach are discussed.

MOLECULAR DOCKING STUDIES OF IMIDAZOLE DERIVATIVES AS NEW CLASS OF HIV-1 PROTEASE INHIBITOR

The human immunodeficiency virus (HIV) infects the immune system that leads to immune deficiency. Acquired immunodeficiency syndrome (AIDS) is defined as the most advanced stages of HIV infection. It is defined by the occurrence of any of more than 20 opportunistic infections or HIV-related cancers. According WHO and UNAIDS estimation, 36.7 million people were living with HIV globally by the end of 2015. 2.1 million People became newly infected, and 1.1 million died of HIV-related causes at the same year. HIV-1 protease plays a vital role in the maturation of virus in order to produce the infectious viral particles. In this study, molecular docking was performed on various imidazole derivatives by Autodock 4.2 into active sites of HIV-1 protease (PDB ID: 4RVI).
