Abstract
In the present research article, we have developed solid heterogenous silica supported lanthanum trifluoroacetate and trichloroacetate as green Lewis acid catalysts. These catalysts were synthesized by a novel, simple, cheap, clean, and environment friendly method. The physicochemical properties of the prepared catalysts were well studied and characterized by sophisticated spectroscopic techniques such as FTIR, TGA, XRD, EDX, SEM, TEM and BET analysis. The catalyst was utilized in the synthesis of arylimidazole derivatives via green protocols under solvent-free conditions at 70 °C with a higher yield, mild reaction conditions and a short reaction time. The catalyst works superiorly in water as well as in various organic solvents as a reusable and easily recoverable catalyst.

Abstract
In the process of drug discovery and development, an efficient and expedient synthetic method for imidazole-based small molecules from commercially available and cheap starting materials has great significance. Herein, we developed a TMSOTf-catalyzed synthesis of trisubstituted imidazoles through the reaction of 1,2-diketones and aldehydes using hexamethyldisilazane as a nitrogen source under microwave heating and solvent-free conditions. The chemical structures of representative trisubstituted imidazoles were confirmed using X-ray single-crystal diffraction analysis. This synthetic method has several advantages including the involvement of mild Lewis acid, being metal- and additive-free, wide substrate scope with good to excellent yields and short reaction time. Furthermore, we demonstrate the application of the methodology in the synthesis of biologically active imidazole-based drugs. Trisubstituted imidazoles are synthesized efficiently from the readily available 1,2-diketones and aldehydes using hexamethyldisilazane as a new and stable nitrogen source under TMSOTf-catalysis system, microwave heating and solvent-free conditions.![]()

Abstract
OBJECTIVE Imidazole is a heterocyclic moiety having immense biological importance. Since ancient times, the imidazole nucleus is considered to be a promising moiety in the field of chemistry. Preliminary in vitro and in vivo studies have provided valuable scientific evidence for its use. Subsequently, imidazole constitutes a new class of compounds for new drug development as the presence of this nucleus in diverse therapeutic categories viz; antimicrobial, anti-inflammatory, anticancer, immunomodulator, antiviral etc. has made it an interesting moiety for the design and development of new pharmacological agents. Thus, this review aims to summarize the reported molecular entities which were synthesized by using conventional as well as microwave processes, chemistry and biological potential of imidazole containing heterocyclic molecules while identifying potential areas of further research on imidazole. RESULTS The review comprises literature pertaining to the evidence-based pharmacological or therapeutic potential of imidazole using published articles and worldwide databases. Various pharmacological experiments using different models exclusively proved the potential of imidazole. SUMMARY Focusing on the discovery and development of new imidazole nucleus based molecules at a faster rate, there is a need to search previous information available in the market in the field of medicinal chemistry. Therefore, the present review aims to elaborate the therapeutic worth of imidazole and its analogs.

Abstract
Due to special properties of ILs (ionic liquids) like their wide liquid range, good solvating ability, negligible vapour pressure, non-inflammability, environmentfriendly medium, high thermal stability, easy recycling and rate promoters etc. they are used in organic synthesis. Therefore, ionic liquids have attracted the attention of chemists and act as a catalyst and reaction medium in organic reaction with high activity. There is no doubt that ionic liquids have become a major subject of study for modern chemistry. More publications in the field have been observed each year, although there is some evidence that this is beginning to plateau at approximately 3500 papers each year. They have been the subject of several major reviews and books, dealing with different applications and aspects of their behavior. Highly efficient methods are explored for the preparation of six-membered two nitrogen-containing heterocycles with the application of IL as a catalyst and reaction medium from 1893 to 2018.
