Kalinin, Alexey V. published the artcileSynthesis of Constrained Raloxifene Analogues by Complementary Use of Friedel-Crafts and Directed Remote Metalation Reactions, Computed Properties of 6972-05-0, the publication is Journal of Organic Chemistry (2003), 68(15), 5992-5999, database is CAplus and MEDLINE.

New constrained heterocyclic analogs of Raloxifene, I [R¹ = 2-(1-piperidinyl)ethoxy, R² = H; R¹ = H, R² = 2-(1-piperidinyl)ethoxy] and II, were prepared by complementary Directed remote Metalation (DreM)/Friedel-Crafts cyclization approaches. Utilization of a benzylidene-thiolactone rearrangement was successfully implemented to construct benzothiophenes III (R³ = Me₂CH, R⁴ = MeO; R³ = Me, PhCH₂, R⁴ = Et₂N) in good yields. Selective deprotection of III (R³ = Me₂CH, R⁴ = MeO; R³ = PhCH₂, R⁴ = Et₂N) induced by complexation was followed by trifluoromethylsulfonylation and Suzuki-Miyaura cross coupling with 3-[2-(1-piperidinyl)ethoxy]phenyl dioxaborolane to give the corresponding 2,4-diaryl-substituted benzothiophenes with methoxycarbonyl or diethylcarbamoyl group in the 3 position. Treatment of the latter with BCl₃ or with excess LDA induced an intramol. para or ortho cyclization and concomitant double deprotection to furnish I. Similar sequence starting from III (R³ = Me, R⁴ = Et₂N) afforded the constrained analog II.

Ranganatha, V. Lakshmi published the artcileSynthesis, characterization, and antimicrobial analysis of 5-phenyl-4-((2-(piperazin-1-yl)ethyl)thio)-1,2,3-oxadiazole analogs through in-vitro and in-silico approach, Application In Synthesis of 118-90-1, the publication is Journal of Molecular Structure (2022), 132168, database is CAplus.

A sequence of novel 1,2,3-oxadiazole derivatives I [R¹ = H, Cl, Br etc; R² = H, methoxy, Br etc; R³ = H, CH₃, Br, etc.] having 2-[(piperazin-1-yl)ethyl]thio moiety were synthesized by multistep synthesis. The newly synthesized compounds I were well characterized and their antimicrobial activities were carried out by disk diffusion and broth dilution methods. Further, among the series of compounds I, compound I [R¹ = R² = H; R ³= Cl] demonstrated a good inhibition against all the tested strains. Also, in-silico analyses including mol. docking simulations, mol. dynamics simulations and binding free energy calculations predicted that the compound I [R¹= R² = H; R³ = Cl] was an extensive and stable interaction with the target proteins. In addition, ADMET anal. also predicted that I [R¹ = R² = H; R³ = Cl] demonstrated no toxicity and carcinogenicity. This makes I [R¹= R² = H; R³ = Cl] one of the potent antimicrobial agents which can be used as a potential drug in the near future.

Bhaskararao, Munukoti published the artcileOne-pot ultrasonication assisted synthesis of biologically active 1,3,4-oxadiazole derivatives catalyzed by TiO₂ nanoparticles, COA of Formula: C8H8O2, the publication is Research Journal of Chemistry and Environment (2022), 26(5), 168-176, database is CAplus.

A novel approach was adopted in the one-pot synthesis of 2-phenyl-5-aryl substituted-1,3,4-oxadiazole derivatives I (R = Ph, 3-methylphenyl, 2-naphthyl, etc.) through ultrasonication. Substituted carboxylic acids RCOOH underwent condensation with benzohydrazide in the presence of ortho-(benzotriazol-1-yl)-N,N,N’,N’-tetramethyluronium tetrafluoroborate (TBTU) to form diacylhydrazine derivatives PhC(O)NHNH(O)R. In the next step, the diacylhydrazine derivatives were subjected to cyclodehydration in the presence of titanium dioxide (TiO₂) nanoparticles (NPs) in the presence of dichloromethane (DCM) solvent, at room temperature through which excellent pure yields of substituted 1,3,4-oxadiazoles I were obtained. The reaction scheme was also performed with other metal oxides NPs (CuO, ZnO, NiO) and the results have shown that TiO₂ NPs were most effective in forming the best yields of the derivatives Their biol. applicability was investigated by conducting anti-bacterial studies against gram-neg. Escherichia coli and gram-pos. Staphylococcus aurues. In these studies, almost majority of the derivatives have shown pos. results in deactivating the micro-organisms.

Xu, Li-Ping published the artcileUnconventional mechanism and selectivity of the Pd-catalyzed C-H bond lactonization in aromatic carboxylic acid, Product Details of C8H8O2, the publication is Nature Communications (2022), 13(1), 315, database is CAplus and MEDLINE.

The search for more effective and highly selective C-H bond oxidation of accessible hydrocarbons and biomols. is a greatly attractive research mission. The elucidating of mechanism and controlling factors will, undoubtedly, help to broaden scope of these synthetic protocols, and enable discovery of more efficient, environmentally benign, and highly practical new C-H oxidation reactions. Here, we reveal the stepwise intramol. S_N2 nucleophilic substitution mechanism with the rate-limiting C-O bond formation step for the Pd(II)-catalyzed C(sp³)-H lactonization in aromatic 2,6-dimethylbenzoic acid. We show that for this reaction, the direct C-O reductive elimination from both Pd(II) and Pd(IV) (oxidized by O₂ oxidant) intermediates is unfavorable. Critical factors controlling the outcome of this reaction are the presence of the ¦Ç³-(¦Ð-benzylic)-Pd and K+-O(carboxylic) interactions. The controlling factors of the benzylic vs ortho site-selectivity of this reaction are the: (a) difference in the strains of the generated lactone rings; (b) difference in the strengths of the ¦Ç³-(¦Ð-benzylic)-Pd and ¦Ç²-(¦Ð-phenyl)-Pd interactions, and (c) more pronounced electrostatic interaction between the nucleophilic oxygen and K⁺ cation in the ortho-C-H activation transition state. The presented data indicate the utmost importance of base, substrate, and ligand in the selective C(sp³)-H bond lactonization in the presence of C(sp²)-H.

Plate, Ralf published the artcileSynthesis, and in vitro and in vivo muscarinic pharmacological properties of a series of 1,6-dihydro-5-(4H)-pyrimidinone oximes, Recommanded Product: O-Isobutylhydroxylamine hydrochloride, the publication is Bioorganic & Medicinal Chemistry (1998), 6(9), 1403-1420, database is CAplus and MEDLINE.

A series of 1,6-dihydro-5-(4H)-pyrimidinone oximes I [R = alkyl, alkenyl, alkynyl, aralkyl] and some of the derived hydroxylamines were synthesized and tested for muscarinic activity in receptor binding assays using [³H]-oxotremorine-M (Oxo-M) and [³H]-pirenzepine (Pz) as ligands. Potential muscarinic agonistic or antagonistic properties of the compounds were determined using binding studies that measured their potencies to inhibit the binding of Oxo-M and Pz. Preferential inhibition of Oxo-M binding was used as an indicator for potential muscarinic agonistic properties; this potential was confirmed in functional studies on isolated organs. The series produced a wide range of active compounds with differing degrees of selectivity in M₁, M₂, and M₃ functional models. Several compounds that have mixed agonist/antagonist profiles were able to reduce cholinergic-related cognitive impairments in models of mnemonic function. Substitutions (I, e.g. R² or R³ = Me) at the 1,6-dihydro-5-(4H)pyrimidine ring disrupted binding and efficacy, whereas systematic variation of the oximes substituent R¹ resulted in various degrees of potency and selectivity dependent on the nature of the substitution.

Preliminary biol. evaluation of thiazoles I and III against the P388 lymphocytic leukemia cell showed growth inhibition values of ED₅₀ 2.9 and 7 ¦Ìg/mL for thiazoles III and I (R = NH₂), resp. Other I were less active.
