The regio- and diastereoselective synthesis of oxazolidinones via a Pd-catalyzed vicinal C-N/C-Cl bond-forming reaction from internal alkenes of allylic carbamates is reported. The oxazolidinones are obtained in yields of 44 to 95% with high to excellent diastereoselectivities (from 6 : 1 to >20 : 1 dr) from readily available precursors. This process is scalable, and the products are suitable for the synthesis of useful amino alcohols. A detailed theoretical and experimental mechanistic study was carried out to describe that the reaction proceeds through an anti-aminopalladation of the alkene followed by an oxidative C-Pd(ii) cleavage with retention of the carbon stereochemistry to yield the major diastereomer. The role of Cu(ii) in a C-Cl bond-forming mechanism step has also been proposed.

Metal-organic frameworks (MOFs) show promise for catalysis applications due to their porosity, high internal surface area, and structural adaptability. Typical acetylation reactions of aldehydes require elevated temperatures and excess alcohol to drive the reactions to completion. In this current work, MOF-808 is used as a heterogeneous catalyst for acetylation of aldehydes in methanol using a mild photothermal process. Optimized conditions gave 72% yield of 2-(dimethoxymethyl)naphthalene in the presence of 10 mol% MOF-808 at 45 degrees C using only a fluorescent lamp. MOF-808 can be recycled up to 5 times with no loss in catalytic activity. A proof-of-principle substrate scope demonstrates the potential utility for aromatic and aliphatic substrates.

A simple and highly efficient protocol for the synthesis of derivatives 7, 7-dimethyl-4-phenyl-2-thioxo-2, 3, 4, 6, 7, 8-hexahydro-1H-quinazoline-5-one from 5, 5-dimethyl cyclohexane-1, 3-dione (4a-4h) (dimedone) has been described. The aryl aldehydes were substituted with thiourea in the presence of synthesized zinc ferrite nanocatalyst, which increased the yield under reflux through condensation, followed by cyclization to give desired products. The other advantages are that it is eco-friendly and economically affordable for large-scale production. Structural validation and characterization of all the newly synthesized compounds were evaluated by spectral analysis (mass spectrometry, proton nuclear magnetic resonance ((HNMR)-H-1), and Carbon-13 nuclear magnetic resonance((CNMR)-C-13)spectroscopies. The structure of antibacterial and antifungal assays was performed with the newly synthesized compounds. The antimicrobial activity of title compounds possessing electron-withdrawing groups such as (4e-4h) (Cl, Br, and cyano group) exhibited more active potential than the electron-donating groups, C6H5,4-C6H4, 3-OC2H5-4OH-C6H3, etc., (4a-4d) containing moiety.

Herein, we report the development of a tailor-made fluoride-based heterogeneous catalyst, POLITAG-F, for the waste-minimized continuous production of cyanohydrin silyl ethers. The careful designing of the polymeric support and the choice of fluoride ion as the anionic species resulted in the improvement of catalytic efficiency and allowed the effective conversion of different carbonyls (aldehydes, ketones, and unsaturated ketones). The POLITAG-F catalyst, employed under flow conditions, led to the conversion of large amounts (over 100 mmol) of the substrate with a productivity of 0.1 mmol min(-1). In addition, flow conditions allowed to minimize the waste production reaching an associated E-factor value of 0.04. An exhaustive evaluation of the environmental impact of our protocol has been reported by considering several green metrics (process mass intensity, atom economy, and reaction mass efficiency) and also the benign index and the safety hazard index of the process.

Essential oils and ethanolic extracts of seeds of seven organically and conventionally grown accessions (E1, E2, E3, E4, E5, E6, and E7) of fennel (Foeniculum vulgare Mill.) were examined for their chemical constituents, antioxidant and antibacterial activities. Accession E7 presented the highest essential oil yields of 4.30 +/- 0.45 and 3.24 +/- 0.46%, respectively, for organic and conventional mode. However, E6 noted the lowest ethanolic extract yield in the two modes of cultivation. Gas chromatography/mass spectrometry analysis of the essential oils revealed the presence of nine essential components in all plant materials. (E)-anethole, methyl-chavicol, fenchone, and limonene were highly abundant. A considerable antioxidant effect was shown for all accessions and a significant difference (p < .05) was reported in the mode of cultivation of essential oils and ethanolic extracts. Concerning antibacterial activity, the essential oils showed generally higher antibacterial activity on gram-positive and gram-negative bacteria than ethanolic extracts for organic and conventional fennel seeds. Practical applications Foeniculum vulgare is an aromatic plant widely used nowadays as flavoring as well as food preservative in foods, such as ice cream, meat, and fish dishes. In this context, the chemical composition and biological activities of essential oil and ethanolic extract from fennel seeds cultivated in organic and conventional modes were studied. Fennel seeds extracts presented a richness in polyphenols and flavonoids. In addition, they showed considerable antioxidant activity, while essential oils had a higher antibacterial activity. There is increase demand, nowadays, for such natural and safe products for future applications in the food industries.

Chromenes and their derivatives are an important class of compounds known for their biological properties. In this study, synthetic methodologies were described to obtain 4H-chromene derivatives. Two routes were investigated, the first being a bicomponent reaction using Knoevenagel adducts as reagents and the second using one-pot tricomponent reactions, both under microwave irradiation, using H2O as solvent and triethylamine as catalyst. Twenty 4H-chromene derivatives were synthesized with 50-95% yields from aromatic aldehydes, 5,5-dimethyl-1,3-cyclohexadione and malononitrile or methyl cyanoacetate, being further characterized by Fourier Transform Infrared and Nuclear Magnetic Resonance. We also report three crystal structures from the synthesized chromene derivatives, by single-crystal X-ray diffraction, showing the main supramolecular features of each structure – a poorly unexplored approach involving this class of compounds so far.

Katritzky salts have emerged as effective alkyl radical sources upon metal- or photocatalysis. These are typically prepared from the corresponding triarylpyrylium ions, in turn an important class of photocatalysts for small molecules synthesis and photopolymerization. Here, a flow method for the rapid synthesis of both pyrylium and Katrizky salts in a telescoped fashion is reported. Moreover, several pyrylium salts were tested in the photoinduced RAFT polymerization of vinyl ethers under flow and batch conditions.

A series of novel N’-(2-thiouracil-5-oyl)hydrazones were designed and chemically synthesized using an active substructure combination method. The synthesized compounds were structurally characterized on the basis of elemental (%) analyses, IR, MS, H-1 NMR, and C-13 NMR spectra. All the prepared compounds were evaluated in vitro against MCF-7 human breast cell line using MTT assay. The anticancer results showed that compounds 3j, 4a, 3c, 3b , and 3h exhibit the most prominent effect against breast cancer cell line with IC50 values of 3.40, 3.50, 3.60, 3.70, and 3.80 mu g/ml, respectively using doxorubicin as a control drug. Moreover, molecular docking studies were also performed in order to identify the binding mode mechanism of these compounds with prospective target, thymidylate synthase (PDB:1JU6). On the other hand, the antibacterial activities of all prepared compounds were screened in vitro against three bacterial strains, namely, Escherichia coli, and Pseudomonas aeruginosa as Gram negative bacteria and Staphylococcus aureus as a Gram positive bacterium using agar well diffusion method. The antibacterial activity results revealed that most of the compounds under test were inactive however, among all the tested compounds, only 3g and 4a , in a concentration of 50 mu g/ml showed a high antibacterial activity against the three used bacterial strained. It is worthy to note that the potency of 3g against Escherichia coli was comparable to that of the reference drug, while compound 2 exhibited significant activity against Pseudomonas aeruginosa only and compound 3j displayed low activity against Staphylococcus aureus. The structure-antibacterial activity relationship analysis can be modulated by the presence of aromatic or heteroaromatic moiety containing more lipophilic character significantly contributed to antibacterial activity. In addition, the drug-likeness properties have predicted for the target compounds. (C) 2021 Published by Elsevier B.V.
