An investigation of the unexpected lability of the Csp(3)-Csp(2)bond connecting 2,4,6-trimethoxyphenyl group and an allylic moiety is carried out. We observed that the catalytic presence of either Lewis or Bronsted acid can render such 2,4,6-trimethoxyphenyl group labile. Several nucleophiles were found to substitute the labile C-C bond in mild reaction conditions resulting in very good yields of the allylated products. Even in the absence of a nucleophile, intramolecular cyclization of the parent substrate under acidic activation caused the labile C-C bond to cleave. A major motivation of this study is to understand the lability of electron-rich aryl group in acidic medium, employing 2,4,6-trimethoxyphenyl moiety as a case study. A plausible mechanism is proposed after carrying out several control reactions as well as UV/Vis and(1)H NMR spectroscopic studies. This work provides an insight into the activation of electron-rich arenes as a labile entity in acidic medium while also adding a conceptually novel C-C bond breaking approach to the vast literature of allylation of arenes.

BACKGROUND: Chemical pesticides are the main measures for pest control, but have caused growing resistance of pests and brought a series of environmental problems. Development of high-efficient insecticidal molecules with novel scaffolds is therefore particularly urgent. RESULTS: Based on a [5 + 1] annulation reaction with 5-amino-1H-phenylpyrazole and dialkyl bromomalonate, 27 novel five-substituted 4,5-dihydropyrazolo[1,5-a]quinazolines were designed following the intermediate derivatization method and synthesized. Bioassay results indicated that most of the test compounds displayed good insecticidal activities against Plutella xylostella, Spodoptera frugiperda, and Solenopsis invicta. In particular, the insecticidal activities of compounds 4a, 4f, and 4m against P. xylostella [median lethal concentration (LC50) values ranged from 3.87 to 5.10 mg L-1] were comparable to that of indoxacarb (LC50 = 4.82 mg L-1). In addition, compounds 4a and 9e showed similar high insecticidal activities against Spodoptera frugiperda (mortality rate = 79.63% and 72.12%) at 100 mg L-1, comparable to that of fipronil (mortality rate: 68.44%); compound 9a showed possible delayed toxicity against Solenopsis invicta (mortality rate: 95.66%) after 5 days of treatment at 1.0 mg L-1. CONCLUSION: Due to their high insecticidal activities against P. xylostella, compound 4m, 4a, and 4f could be considered as qualified candidates for novel insecticide. Several other 4,5-dihydropyrazolo[1,5-a]quinazolines with relatively high bioactivity, such as compounds 9a and 9e, are also worth further optimization as potential insecticide or anticide candidates.

Cellulose benzoate propionates (CBzP) were prepared via a staged addition of Pr2O followed by Bz(2)O to cellulose dissolved in tributylmethylammonium dimethyl phosphate (TBMADMP) providing regioselectively substituted cellulose esters in which the benzoate was preferentially installed at C2 and C3. By systematically varying the DSPr, DSBz, and DSOH (DS = degree of substitution), we synthesized CBzP that could potentially be utilized as a unique compensation film in optical displays.

A new series of novel chromene-based oxadiazole derivatives were synthesized from a variety of chromene-based amidoximes with readily available carboxylic acids under conventional oil bath heating as well as under microwave irradiation. The use of commercially available EDCI and HOBt as coupling reagents in DMF combined with microwave heating resulted in high yields and purities of the product 1,2,4-oxadiazoles in an expeditious manner. This methodology is successfully applied to synthesize 18 numbers of new 2H-chromene-substituted 1,2,4-oxadiazole derivatives in good to high yields. The structure of the product was ascertained by X-ray crystallographic analysis. All the synthesized compounds were evaluated for their in vitro antibacterial activity against two different pathogenic bacterial strains, that is, Escherichia coli (MTCC614) and Klebsiella pneumoniae (MTCC4031). The obtained results from in vitro antimicrobial assays indicated that 6g and 6h exhibited good antibacterial activity nearer to the standard drug, gentamicin. The molecular docking studies showed that compounds 6g and 6h show hydrogen bonding interaction with the bacterial target DNA gyrase of E. coli.

New benzothiazole-based derivatives were synthesized in the present work with the aim of evaluating their antitumor activity. They were in vitro tested against hepatocellular carcinoma (HepG2), colorectal carcinoma (HCT-116), mammary gland cancer (MCF-7), prostate cancer (PC-3), and epithelioid carcinoma (HeLa). The results of the in vitro antitumor evaluation revealed that the most active compounds were 39, 40, 51, 56, and 61 exhibiting IC50 values comparable to the reference drug lapatinib. The most active compounds were further subjected to EGFR inhibitory activity assay to rationalize their potency mode. Notably, the most active antitumor compounds 39 and 40 represented the most potent inhibitors to EGFR with IC50 values of 24.58 and 30.42 nM respectively in comparison with 17.38 nM for lapatinib as a standard drug. Molecular modeling studies were also conducted for the synthesized compounds, including docking into EGFR active site and surface mapping. Results proved the superior binding of the hydrazone derivatives 39 and 40 with EGFR suggesting them as good candidates for targeted antitumor therapy through EGFR kinase inhibition.

Nano copper ferrite catalyst is prepared and characterized by scanning electron microscopy, energy dispersive X-ray, X-ray diffraction, vibrational sample magnetometry, and Fourier transform infrared. The catalytic activity is probed for cross-dehydrogenative coupling of aromatic aldehydes in the presence of tert-butyl hydroperoxide as the oxidant. This catalytic protocol appears as a simple, rather cheap, clean, and efficient practical strategy for the synthesis of symmetrical anhydrides, with proper efficiency (66%). The catalyst can be easily separated from the reaction mixture by an external magnet and reused several times in subsequent reactions, without any measurable loss of its efficiency. [GRAPHICS] .

A metal-free aromatic electrophilic substitution reaction using nitrosoarenes as the electrophile in 1,1,1,3,3,3-hexafluoroisopropanol (HFIP) is reported. HFIP activates nitrosoarene towards the electrophilic C-H amination followed by a concomitant N-O bond cleavage to deliver diarylamines without requiring any extra reagent or further treatment. The dual electrophilic nature of nitrosoarene permits a switchover of selectivity to C-H oxygenation furnishing dearomatizedp-iminoquinones following a unique mechanistic rationale of two consecutive [2,3] sigmatropic rearrangement in nitroso-chemistry.

In this work, a monomer-mediated in situ growth strategy was developed for the controllable construction of core-shell Co3O4@TAPB-DMTP-COF composite (TAPB, 1,3,5-tris(4-aminophenyl)benzene; DMTP, 2,5-dimethoxyterephaldehyde; COF, covalent organic framework), which exhibits uniform size, high surface area, outstanding thermochemical stability, and ultrahigh effective surface area. The Co3O4@TAPB-DMTP-COF was further applied to develop an electrochemical sensor for the sensitive and selective determination of tertbutylhydroquinone (TBHQ). Mechanism investigations reveal that multistacked columnar channels given by TAPB-DMTP-COF shell can effectively facilitate the diffusion of TBHQ molecules to the active Co3+ sites. Under the optimal conditions, the current response exhibits two linear dynamic ranges, 0.05-1.0 and 1.0-400 mu mol L-1, and the detection limit was as low as 0.02 mu mol L-1 (S/N = 3). Little to no interference effects from other coexisting ions allows the sensor to detect low-abundance TBHQ from complicated real samples. This study not only provides a strategy for crystalline and shape-tailored growth of COF shells, but also expands their further use in electrochemical sensor.
