Palladium-catalyzed functionalizations of acidic and non-acidic C(sp(3))-H bonds – recent advances

A tremendous upsurge has been seen in the recent decade for the proximal and remote functionalization of activated and unactivated substrates via palladium redox pathways. This feature article discusses some of the recent reports on direct as well as indirect C(sp(3))-H functionalization via cross-coupling reactions under palladium catalysis. Activated substrates (possessing acidic C(sp(3))-H) including enones, ketones, aldehydes, silylenol ethers, esters, silyl ketene acetals, amides, cyano, alpha-amino esters, and O-carbamates, capable of undergoing cross-coupling reactions at the alpha-, beta-, gamma-, delta- and epsilon-positions, will be discussed. To overcome the challenging task of achieving regioselectivity, a variety of innovative modifications have been reported. The reports of C-H activations based on directing group, and as native functionality have been illustrated at the beta-, gamma- and delta-positions. Substrates such as alpha-amino esters, carbonyls, carboxylic acids and their derivatives, afford site-selective C(sp(3))-H functionalization via varied-sized reactive metallacycles and are a unique class of substrates whose C(sp(3))-H functionalizations were earlier considered as very difficult.

5-Ene-4-thiazolidinones – An efficient tool in medicinal chemistry

The presented review is an attempt to summarize a huge volume of data on 5-ene-4-thiazolidinones being a widely studied class of small molecules used in modern organic and medicinal chemistry. The manuscript covers approaches to the synthesis of 5-ene-4-thiazolidinone derivatives: modification of the C5 position of the basic core; synthesis of the target compounds in the one-pot or multistage reactions or transformation of other related heterocycles. The most prominent pharmacological profiles of 5-ene derivatives of different 4-thiazolidinone subtypes belonging to hit-, lead-compounds, drug-candidates and drugs as well as the most studied targets have been discussed. Currently target compounds (especially 5-en-rhodanines) are assigned as frequent hitters or pan-assay interference compounds (PAINS) within high-throughput screening campaigns. Nevertheless, the crucial impact of the presence/nature of C5 substituent (namely 5-ene) on the pharmacological effects of 5-ene-4-thiazolidinones was confirmed by the numerous listed findings from the original articles. The main directions for active 5-ene-4-thiazolidinones optimization have been shown: i) complication of the fragment in the C5 position; ii) introduction of the substituents in the N3 position (especially fragments with carboxylic group or its derivatives); iii) annealing in complex heterocyclic systems; iv) combination with other pharmacologically attractive fragments within hybrid pharmacophore approach. Moreover, the utilization of 5-ene-4-thiazolidinones in the synthesis of complex compounds with potent pharmacological application is described. The chemical transformations cover mainly the reactions which involve the exocyclic double bond in C5 position of the main core and correspond to the abovementioned direction of the 5-ene-4-thiazolidinone modification.

Synthesis and Characterization of Piperine Analogs as Potent Staphylococcus aureus NorA Efflux Pump Inhibitors

The efficient synthesis of novel 2,2-dimethyl-chroman-6-yl pentadienoic acid amides (7a-e) as synthetic piperine analogs has been established by the condensation of 5-(2,2-dimethyl-chroman-6-yl)-4-methyl-penta-2,4-dienoic acid 6 with various aromatic amines. All the synthesized piperine analogs were bioevaluated for their potential as inhibitors of multidrug efflux pump NorA overexpressing Staphylococcus aureus SA 1199B. Out of all the prepared analogs, 5-(2,2-dimethyl-chroman-6-yl)-4-methyl-penta-2,4-dienoic acid ethyl ester 5 and 5-(2,2-Dimethyl-chroman-6-yl)-4-methyl-2E,4E-pentadienoic acid pyrrolidide 7d were found promising. The active compounds were also evaluated for their synergistic effect with ciprofloxacin, whose results substantially increase the activity of ciprofloxacin against both Nora overexpressing and wild type Staphylococcus aureus isolates. Structures of the synthesized compounds have been elucidated on the basis of spectral data (IR, H-1 NMR and Mass analysis).

N-rich porous organic polymers based on Schiff base reaction for CO2 capture and mercury(II) adsorption

Due to the p-pi conjugative effect between the nitrogen atom of the amide and the carbonyl, the amide carbonyl has much low reactivity and the Schiff base reaction between the amide and amine usually did not take place, but after the amide was polymerized, it’s quite different. Herein, benzene-1,3,5-triyl tris((9H-carbazol-9-yl) methanone) (HTCZ) is not able to have the Schiff base reaction with melamine. Surprisingly, after HTCZ was polymerized according to the Friedel-Crafts reaction, the resultant polymer PHTCZ-1 performed the Schiff base reaction with melamine successfully, and a kind of novel N-rich porous organic polymers, namely, PHTCZ-1-MA was successfully synthesized. Moreover, PHTCZ-1-MA owned much higher Brunauer-Emmett-Teller surface area (613 m(2).g(-1)) and pore volume (0.57 cm(3).g(-1)) with very high nitrogen content (42.39 wt%). The theoretical calculation showed that the positive charge of the carbonyl carbon increased by 18% after the polymerization, which greatly improved the reactivity of the carbonyl. Because of this amazing change, PHTCZ-1-MA was proven to be an excellent adsorbent for CO2 capture (180 mg.g(-1) at 273 K and 1.0 bar) and mercury(II) adsorption (335 mg.g(-1) at 273 K). This study makes the impossibility possible and provides a unique synthesis strategy for the fabrication of a kind of N-rich porous organic polymers. (c) 2020 Elsevier Inc. All rights reserved.

Ionic liquids with anions based on fluorosulfonyl derivatives: from asymmetrical substitutions to a consistent force field model

Herein, seven anions including four imide-based, namely bis[(trifluoromethyl) sulfonyl] imide (TFSI), bis(fluorosulfonyl) imide (FSI), bis[(pentafluoroethyl) sulfonyl] imide (BETI), 2,2,2-trifluoromethylsulfonyl-N-cyanoamide (TFSAM) and 2,2,2-trifluoro-N-(trifluoromethylsulfonyl) acetamide (TSAC), and two sulfonate anions, trifluoromethanesulfonate (triflate, TF) and nonafluorobutanesulfonate (NF), are considered and compared. The volumetric mass density and dynamic viscosity of five ionic liquids containing these anions combined with the commonly used 1-ethyl-3-methylimidazolium cation (C(2)C(1)im), [C(2)C(1)im][FSI], [C(2)C(1)im][BETI], [C(2)C(1)im][TFSAM], [C(2)C(1)im][TSAC] and [C(2)C(1)im][NF] are measured in the temperature range of 293.15 <= T/K <= 353.15 and at atmospheric pressure. The results show that [C(2)mim][FSI] and [C(2)mim][TFSAM] exhibit the lowest densities and viscosities among all the studied ionic liquids. The experimental volumetric data is used to validate a more consistent re-parameterization of the CL&P force field for use in MD simulations of ionic liquids containing the ubiquitous bis[(trifluoromethyl) sulfonyl] imide and trifluoromethanesulfonate anions and to extend the application of the model to other molten salts with similar ions.

The Ritter Reaction of 2-Oxoaldehydes at Room Temperature: Divergent Behaviour towards Acid Strength

An efficient, novel, atom economical and selective amidation method for the generation of mono and di-Ritter products using 2-oxoaldehydes under acidic environment at room temperature was successfully developed. The di-Ritter products obtained are accessed in good yields when stirred in the presence of 20 mol % H2SO4, and the mono products were selectively obtained in moderate yields with CuOTf as catalyst. However, the yields of the latter were optimized by the addition of SeO2.

Catalytic challenges and strategies for the carbonylation of sigma-bonds

The carbene character of carbon monoxide offers the possibility to utilize this C-1-building block for the carbonylation of a variety of organic substrates by insertion of CO into sigma-bonds. Although presenting an ideal atom economy this route requires the design and utilization of reactive catalysts able to activate strong C-O, C-N, and C-H bonds in the presence of carbon monoxide. This perspective article addresses, in the context of sustainable chemistry, the challenges and strategies facing the catalytic carbonylation of sigma-bonds and presents the key advances in the field over the last few decades, for the carbonylation polar and apolar substrates, such as the conversion of alcohols to formates and esters and the carbonylation of amines to amides.

Evaluation of vinburnine in pharmaceuticals by smart spectrophotometric methods; full stability study

Vinburnine (VNB) is a vinca alkaloid used as a vasodilator to enhance cerebral circulatory insufficiency. It is a cyclic amide containing drug which is expected to be sensitive to hydrolytic degradation. The degradation profile of VNB was studied in this work following ICH recommendations for stability study. The drug was sensitive only to degradation with NaOH with the formation of the carboxylic acid derivative, identified by IR and H-1 NMR analyses as 2-((1S,12bS)-1-ethyl-1,2,3,4,6,7,12,12b-octahydroindolo[2,3-a] quinolizin-1-yl) acetic acid, (DEG). In this study five simple, smart and univariate stability indicating spectrophotometric methods were developed and validated for simultaneous determination of VNB and DEG for the first time. The developed methods include; Dual Wavelength Method (DWM), Dual Wavelength Resolution Method (DWRM), Factorized Absorbance Difference Method (FADM), Advanced Absorbance Subtraction Method (AASM), and Derivative Amplitude Factor Method (DAFM). These methods were capable of determination of VNB and DEG over the ranges of 1-30 and 3-50 mu g/mL, respectively. The proposed methods were simple, smart, specific, and could be applied for analyzing synthetic mixtures of VNB and DEG and were successfully applied for determination of the drug in commercially available capsules. The obtained results of these methods were statistically compared with the reported HPLC one using student’s-t and F- tests, where no significant difference was observed. Validation of the developed methods was applied according to ICH recommendations and all the results were within the acceptable limits. Published by Elsevier B.V.
