Selenocyano fragments with distinct structural characteristics were successfully incorporated into the 5- and 7-positions of chrysin via etherification and esterification of its hydroxyl groups. Eleven novel chrysin selenocyanates were synthesized, and their structures characterized by NMR and HRMS. The activities of all compounds were evaluated against human cervical cancer cell lines HeLa, ovarian cancer cell lines SKOV-3, and breast carcinoma cell lines MCF-7 using MTT assays. Results indicated that esterified chrysin derivatives significantly inhibited HeLa cells, while alkylated chrysin ethers showed notable activity against SKOV-3 and MCF-7 cells. Compounds 5c and 5e exhibited the strongest inhibitory effects on SKOV-3 cells, with IC50 values of 2.27 ± 0.19 μM and 2.51 ± 0.33 μM, respectively. The introduction of diselenocyanate at both the 5- and 7-positions demonstrated superior inhibitory activity compared to a single selenocyanate at the 7-position alone. The findings may aid in designing novel chemotherapeutic drugs.

Using one-pot multicomponent reactions, two new series of imidazoles (4a–o and 6a–d), were synthesized due to their great biological activity. The first series was accomplished by the reaction of O-alkyl vanillins 1a–c, ammonium acetate 2, and benzil derivatives 3a–e in ethanol, while the second series was obtained by reacting O-alkyl vanillins 1a, ammonium acetate 2, benzil 3a, and amino compounds (aniline 5a or amino acids 5b–d) in acetic acid. The in vitro antibacterial activity of the novel synthetic imidazoles was assessed against strains of gram positive bacteria, such as Bacillus cereus and Staphylococcus aureus, and gram negative bacteria, such as Pseudomonas aeruginosa and Escherichia coli. The findings indicated that some of the evaluated items have promising antibacterial agents, especially imidazoles 4d and 4e for (+G) bacteria and imidazoles 4c and 4f for (−G) bacteria.

An efficient and environmentally friendly methodology has been developed for the synthesis of 1,5-benzodiazepine derivatives, employing catalytic amounts of guanidine hydrochloride in aqueous conditions. The desired compounds were obtained with high yields by combining variously substituted aryl aldehydes with o-phenylene diamine and dimedone. The protocol offers several advantages, including a rapid reaction time, the use of greener solvents, simple workup procedures, and an uncomplicated purification process, ensuring energy efficiency and versatility. Also, the catalyst can be recycled up to 4-5 cycles without compromising the overall yield, adding to the overall merit of this method. Furthermore, green chemistry metrics such as EcoScale, E-Factor, and Process Mass Intensity (PMI) were employed to evaluate the environmental impact of the process thoroughly.

The current study describes a new preparation of loxoprofen. The whole process includes five steps from cheap cyclopentanone and methyl 4-bromophenylacetate as the starting materials. The key intermediate is obtained through Mizoroki-Heck reaction of 2-methylenecyclopentanone and methyl 2-(4-bromophenyl)propanoate. The desired loxoprofen is yielded through hydrogenation followed by hydrolysis in 56% overall yield with 99.7% purity.

Imidazole, a five-membered heterocyclic compound, has multipurpose applications for its bioactivity, uses in charge transport materials, and NLO materials. The review provides a comprehensive survey of the synthetic strategies of imidazole from various starting materials, highlighting their percentage yield and mechanistic insights. The most popular starting materials for the syntheses of imidazole include diketones, cyanides, imines, amidines, imidamides, di-amines, and oximes. Although the selection of a particular synthetic strategy will depend largely on the desired imidazole derivative, the survey consists of more than a century of research on imidazole synthetic procedures, starting with Heinrich Debus synthesis in 1858 till the present day. Most recent advancements and future perspectives in the field have been explored. The study will help researchers choose the most suitable starting material, catalyst, solvent, or reaction conditions for the synthesis of various imidazole derivatives.

Imidazo[1,2-a]pyridine derivatives possess widespread applications in the pharmaceutical industry and bioactive natural products. The diverse functionalization of this skeleton has attracted much attention from chemists. Herein, we reported an electrochemical deoxygenative alkoxycarbonylation of imidazoheterocycles by using electrons as the traceless oxidant under mild and oxidant-free conditions. Notably, our strategy provided a green and practical approach for introducing ester group into imidazo[1,2-a]pyridine derivatives by employing easily available and bench-stable carbazates as ester source.

A deacylation method was developed based on lysine-assisted methanolysis of nucleoside-derived esters and arylamides. The present methodology complements well-established deacylation methods, using a minimum molar equivalency of lysine and methanol under mild heating to generate the deacylated nucleoside and recyclable lysine and volatile methyl esters as byproducts. A variety of acylated canonical nucleosides and hydrolytically labile non-canonical nucleosides like nicotinamide riboside (NR) and its reduced form (NRH) were deprotected under such lysine-assisted conditions, demonstrating the versatility of this approach. Having determined this one-pot process’s E-factor and reaction mass index, we find this method greener than the more established deacylation processes.

The catalyst-free oxidative deamination without over-oxidation constitutes a considerable challenge in the synthesis of aromatic aldehydes. Herein, we introduce a Selectfluor-mediated Lewis acid system that achieves the oxidative deamination of benzylic amines with α-C-H bond activation to yield aromatic aldehydes. Noteworthy features include the direct use of Selectfluor that can activate the α-C-H bond under catalyst- and base-free conditions via the in-situ dehydrofluorination effect. The approach is demonstrated for a broad scope of benzylic amines without over-oxidation and accomplishes 200 mmol scale synthesis.

The aryl-azaindole-pyrimidine-1,3,4-oxadiazole derivatives (12a–j) were synthesized by Suzuki coupling reaction between bromo-azaindole-1,3,4-oxadiaole intermediate 10 and various aryl boronic acids (11a–j) by using of Pd(dppf)Cl2 and K2CO3 in 1,4-dioxane/H2O. Here, the Suzuki coupling mechanism starts with the oxidative addition followed by transmetallation and ends with reductive elimination. These derivatives were screened in vitro anticancer applications against four human cancer cell lines including MCF-7, A549, Colo-205, and A2780 by employing of MTT method, the well-known chemotherapeutic agent as etoposide used as positive control. Among them, compound 12a bearing 3,4,5-trimethoxy substituent on the aryl moiety displayed good activity as compared with positive control against MCF-7, A549, Colo-205, and A2780 cell lines with IC50 values of 1.10 ± 0.84 µM, 1.07 ± 0.067 µM, 1.20 ± 0.95 µM, and 1.34 ± 0.66 µM respectively. Compounds 12a and 12b primarily engage in hydrophobic interactions such as pi-pi stacked, amide-pi stacked, pi-alkyl, and alkyl interactions. Specifically, nucleotides DG13, DA12, and arg503 display pi-pi stacked and amide-pi stacked interactions.
