Although the synthesis of novel N-heterocyclic molecules is extremely demanding as well as challenging, the involvement of toxic solvents often triggers environmental safety concerns, resulting in process-engineering challenges. Herein, we have demonstrated a rapid, environmentally benign and energy efficient scalable method for the synthesis of 2,3-dihydroquinazolin-4(1H)-one by grinding in a mortar pestle as well as mechanochemically via ball milling using p-TSA catalyst. The ability to accomplish the reaction in the absence of solvent via grinding or milling with p-TSA catalyst, with an immediate reduction in the cost and operational procedures, features the significant advantages of this protocol. The scalability and significance of the operational parameters during mechanochemical milling in the tubular ball mill were also demonstrated. Excellent yield in short duration, large substrate scope, product scalability, and easy recoverability are the prime features of this mechanochemical solvent-free protocol for the synthesis of 2,3-dihydroquinazolin-4(1H)-one. The study also demonstrated the significant role of ball diameter to improve the efficiency of the milling operation in this mechanochemical synthesis.

The enantioselective Henry reaction is a very important and useful carbon-carbon bond forming reaction. The execution of this reaction requires the use of efficient chiral catalysts. In this work, in situ formed complexes of N-substituted dihydroxypyrrolidines, chiral ligands derived from L-tartaric acid and amines, were evaluated as catalysts in the enantioselective Henry reaction. The results showed that the nature of the N-substituent on the ligand significantly influences the outcome of the reaction. Best results were obtained using a Cu (II) complex of (3S,4S)-N-benzyl-3,4-dihydroxypyrrolidine, in the presence of DIPEA, for the reaction of aromatic aldehydes with nitromethane, at room temperature, originating products with er up to 92:8 (R:S) and conversions up to 96%. The interaction between the pyrrolidine ligand and the copper ion, in isopropanol, was followed by UV-vis spectrophotometry, showing a 1:1 stoichiometry and a binding constant of 4.4. The results obtained will contribute to the design and development of more efficient chiral catalysts for this type of reaction.

Hosseini, A; Schreiner, PR in [Hosseini, Abolfazl; Schreiner, Peter R.] Justus Liebig Univ Giessen, Inst Organ Chem, Heinrich Buff Ring 17, D-35392 Giessen, Germany published Direct Exploitation of the Ethynyl Moiety in Calcium Carbide Through Sealed Ball Milling in 2020, Cited 71. The Name is Anthrone. Through research, I have a further understanding and discovery of 90-44-8.

Ball milling of calcium carbide (CaC2) enables the reaction of its ethynyl moiety with organic electrophiles. This was realized simply by co-milling CaC(2)with organic substrates in a sealed jar without the need for an additive or a catalyst. Various ketones including those bearing alpha-hydrogens were ethynylated in good yields at short reaction times. Aryl halides are also amenable substrates for this protocol as they furnish aryl ethynes through a benzyne intermediate. This method offers a practical and cheap alternative to the established procedures for introducing ethynyl functionalities.

We report here a C-H homoallylation reaction of aromatic ketones with methylenecyclopropanes (MCPs) only using a catalytic amount of Fe(PMe3)(4). A variety of aromatic ketones and MCPs are applicable to the reaction to form ortho-homoallylated aromatic ketones selectively via regioselective scission of the three-membered rings. The homoallylated products are amenable to further elaborations, providing functionalized 1,2-dihydronaphthalenes.

N-Formamide synthesis usingN-formyl imide with primary and secondary amines with catalytic amounts ofp-toluenesulfonic acid monohydrate (TsOH center dot H2O) is described. This reaction is performed in water without the use of surfactants. Moreover,N-formyl imide is efficiently synthesized using acylamidines with TsOH center dot H2O in water. In addition,N-formyl imide was successfully used as a carbonyl source in the synthesis of benzimidazole and quinazolinone derivatives. Notable features ofN-formylation of amines by usingN-formyl imide include operational simplicity, oxidant- and metal-free conditions, structurally diverse products, and easy applicability to gram-scale operation.

A series of 4-thiazolinone derivatives (D1-D58) were designed and synthesized. All of the derivatives were evaluated in vitro for neuraminidase (NA) inhibitory activities against influenza virus A (H1N1), and the inhibitory activities of the five most potent compounds were further evaluated on NA from two different influenza viral subtypes (H3N2 and B), and then their in vitro anti-viral activities were evaluated using the cytopathic effect (CPE) reduction assay. The results showed that the majority of the target compounds exhibited moderate to good NA inhibitory activity. Compound D18 presented the most potent inhibitory activity with IC50 values of 13.06 mu M against influenza H1N1 subtype. Among the selected compounds, D18 and D41 turned out to be the most potent inhibitors against influenza virus H3N2 subtype (IC50 = 15.00 mu M and IC50 = 14.97 mu M, respectively). D25 was the most potent compound against influenza B subtype (IC50 = 16.09 mu M). In addition, D41 showed low toxicity and greater potency than reference compounds Oseltamivir and Amantadine against N1-H275Y variant in cellular assays. The structure-activity relationship (SAR) analysis showed that introducing 4-CO2H, 4-OH, 3-OCH3-4-OH substituted benzyl methylene can greatly improve the activity of 4-thiazolinones. Further SAR analysis indicated that 4-thiazolinone and ferulic acid fragments are necessary fragments of target compounds for inhibiting NA. Molecular docking was performed to study the interaction between compound D41 and the active site of NA. This study may providing important information for new drug development for anti-influenza virus including mutant influenza virus. (C) 2021 Elsevier Masson SAS. All rights reserved.

In this study, we describe the synthesis and molecular properties of anthranilamide-based short peptides which were synthesised via ring opening of isatoic anhydride in excellent yields. These short peptides were incorporated as low molecular weight gelators (LMWG), bola amphiphile, and C-3-symmetric molecules to form hydrogels in low concentrations (0.07-0.30% (w/v)). The critical gel concentration (CGC), viscoelastic properties, secondary structure, and fibre morphology of these short peptides were influenced by the aromaticity of the capping group or by the presence of electronegative substituent (namely fluoro) and hydrophobic substituent (such as methyl) in the short peptides. In addition, the hydrogels showed antibacterial activity against S. aureus 38 and moderate toxicity against HEK cells in vitro.
