The main aim of the present work was to conduct the one-pot microwave-assisted green synthesis of benzil and its derivatives. Benzil is acknowledged as a pivotal scaffold in the realm of medicinal and organic chemistry, owing to its extensive utilities. Due to the various merits of the green technology approach compared to classical methodology and the provision of sustainable chemistry, this reaction has received re Read More

HSP90 assists as a crucial molecular chaperone that responds to environmental stressors and helps in the survival of cells in microorganisms. This protein is integral to the stress response, aiding in the stabilization of various proteins essential for microbial survival. Consequently, the ability of a number of tissues to adjust to endogenous stress depends critically on appropriate chaperone activity. Modulators of chaperone activity, Read More

The amide group is one of the most ubiquitous chemical motifs in the pharmaceutical field. An efficient continuous flow synthesis of amides was achieved by coupling acids with amines using 2-bromo-1-ethylpyridinium tetrafluoroborate (BEP) in the bio-derived “green” solvent γ-valerolactone (GVL). The reaction proceeded under mild reaction conditions (ambient temperature, 1 min) with simple filtration without the need for e Read More

The objective of the study was to develop new Oxadiazole compounds using docking simulation studies for inhibitory action against the Cycloxoygenase-2(COX-2) enzyme. The study aimed at the development and identification of novel and potent derivatives of 1,3,4-oxadiazole for targeting anti-inflammatory disease by screening their inhibitory action against COX-2 enzyme with schrodinger molecular docking softw Read More

In the current study, we reported a cost-effective, simple strategy for the synthesis and reactivity of a novel series of chromenopyridine derivatives involving 2,4-diamino-3-carbonitrile moieties. These new compounds were synthesized in good yields from malononitrile and various chromene derivatives as a precursor, which was prepared by the reduction of iminocoumarin derivatives. The formed iminocoumarin was obtained Read More

Tulsion®-8052 MP cation resin catalyst accelerates chemical reaction by creating a suitable environment for the aldehyde and indole reactants to interact and form desired product bis(indolyl) methanes in solvent-free room temperature conditions. The uniqueness of this catalytic method is that it is eco-friendly, recyclable, selective, and operates on a variety of functional groups with good to excellent yield at room temperat Read More

This work is devoted to the synthesis of divers Michael adducts from (E)-α-atlantone as an α,β-unsaturated ketone isolated from Cedrus atlantica essential oil. The (E)-α-atlantone is subjected to ethyl cyanoacetate, phenylmagnesium bromide, and ethanol to produce the corresponding 1,4-Michael adducts in good yields. The conjugate addition of the appropriate reagents onto (E)-α-atlantone proceeds in a regiospecific man Read More

Betulinic acid and its various synthetic derivatives have been reported to possess diverse biological activities and some of these may serve as useful therapeutic agents for a variety of human disorders. In this perspective, we have now developed convenient one-pot syntheses of new C-28 esters (2-7) of betulinic acid by esterification of the carboxylic moiety of betulinic acid (1) with various alkylating agents. All the target co Read More
