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.

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.

Photophysical studies of fused phenanthrimidazole derivatives as versatile pi-conjugated systems for potential NLO applications

Two new heterocyclic imidazole derivatives consists of pi-conjugated system attached to a phenanthrimidazole moiety have been synthesized in moderate yield by the condensation of 1,10-phenanthroline-5,6-dione with substituted aromatic aldehydes and 4-methoxyaniline in the presence of ammonium acetate in ethanol medium. The photophysical properties of these imidazole derivatives were studied in several solvents. These derivatives were evaluated concerning their solvatochromic properties and molecular optical nonlinearities. Their electric dipole moment (mu) and hyperpolarizability (beta) have been calculated theoretically and the results indicate that the extension of the pi-framework of the ligands has an effect on the NLO properties of these imidazole derivatives. The non-zero tensor components of these imidazole derivatives reveal that they possess potent non-linear optical (NLO) behavior. The energies of the HOMO and LUMO levels and the molecular electrostatic potential (MEP) energy surface studies have exploited the existence of intramolecular charge transfer (ICT) within the molecule.

Fatty acid hydroperoxide lyase (HPL) is a key enzyme in the biosynthesis of plant volatiles involved in defense responses to mechanical or herbivore-induced wounding. We report here the synthesis of imidazole derivatives and their inhibitory activities on the tomato 13-HPL subfamily.

Optical difference spectroscopy analysis of compound 3 and HPL interaction indicated that this compound induces a type II binding spectra with a K(d) value of approximately 13.5 mu M.

CALCULATION OF TAUTOMER PREFERENCE FOR RIGID IMIDAZOLE DERIVATIVES

The tautomeric preference of rigid imidazole derivatives has been analyzed theoretically from molecular orbital calculations ab initio. The present results indicate that the reduced potencies exhibited by imidazolylphenylene analogues of cimetidine and metiamide at the H2-receptor are consistent with those hypotheses that defined the N3-H tautomer of the monocation as the only recognizable species in this class of histamine H2-ligand. However, our results suggest that the 4-methylimidazolylphenylene analogue of cimetidine could be an effective histamine H3-antagonist.
