An efficient three-component benzoselenophenes formation has been developed from substituted indoles, acetophenones, and selenium powder under metalfree conditions. 2-Aryl indoles played an important role to promote benzoselenophene formation from acetophenone derivatives and selenium powder. One C-C and two C-Se bonds were selectively formed to provide 40 new benzoselenophenes in good yields.

Ethyl 2-[8-Arylmethylidenehydrazino-3-methyl-7-(1-oxothietan-3-yl)xanth-1-yl]acetates (IV) were synthesized via reactions of ethyl 2-[8-hydrazino-3-methyl-7-(1-oxothietan-3-yl)xanth-1-yl]acetic acid (III) with various benzaldehydes and acetophenones. The structures of the compounds were elucidated using IR and NMR spectroscopy and elemental analysis. The antiplatelet, anticoagulation, antioxidant, and anti-inflammatory activities were assessedin vitroand in laboratory animals to identify promising compounds exhibiting antiplatelet (hydrazoneIVd) and antioxidant properties (hydrazoneIVb). BothIVbandIVdaccording toin silicocalculations were characterized by the absence of toxic risks (mutagenicity, oncogenicity, reproductive toxicity, local irritation) and had acceptable topological polar surface area so that they were promising.

Prabhakaran, P; Rajakumar, P in [Prabhakaran, Perumal; Rajakumar, Perumal] Univ Madras, Dept Organ Chem, Guindy Campus, Chennai 600025, Tamil Nadu, India published Regio- and stereoselective synthesis of spiropyrrolidine-oxindole and bis-spiropyrrolizidine-oxindole grafted macrocycles through [3+2] cycloaddition of azomethine ylides in 2020.0, Cited 143.0. Formula: C8H7NO3. The Name is 1-(4-Nitrophenyl)ethanone. Through research, I have a further understanding and discovery of 100-19-6.

A convenient and efficient method for the regioselective macrocyclization of triazole bridged spiropyrrolidine-oxindole, and bis-spiropyrrolizidine-oxindole derivatives was accomplished through intra and self-intermolecular [3 + 2] cycloaddition of azomethine ylides. The chalcone isatin precursors 9a-i required for the click reaction were obtained from the reaction of N-alkylazidoisatin 4 and propargyloxy chalcone 8a-i which in turn were obtained by the aldol condensation of propargyloxy salicylaldehyde 6 and substituted methyl ketones 7a-i. The regio- and stereochemical outcome of the cycloadducts were assigned based on 2D NMR and confirmed by single crystal XRD analysis. High efficiency, mild reaction conditions, high regio- and stereoselectivity, atom economy and operational simplicity are the exemplary advantages of the employed macrocyclization procedure.

Hydrogen peroxide (H2O2) can be produced in mitochondria and plays a significant role in physiological metabolism. Overproduction of H2O2 is a hallmark of many diseases. Therefore, it is very important to develop a highly sensitive method for detecting H2O2 both in vivo and in vitro. Previously reported benzil-based fluorescence probes are superior to those based on boronate ester in terms of reaction selectivity. However, the near infrared (NIR) probe with biocompatibility has been rarely reported for the detection of endogenous hydrogen peroxide and the real-time imaging in biological system. Hemicyanine skeleton has been proven to be effective scaffold for NM fluorescent probes for non-invasive optical imaging in vivo. In this paper, a Cy-H2O2 probe for real-time monitoring hydrogen peroxide in organisms was designed by modifying the NIR hemicyanine framework with benzil moiety. The results showed that Cy-H2O2 exhibits high specificity and sensitivity, and has good water solubility and short response time (within 10 min) for detection of hydrogen peroxide in vitro and in vivo. The reaction mechanism was deduced by detecting product of the fluorescent probe reacting with hydrogen peroxide using HPLC. The probe shows a good linear relationship for the specific response to H2O2 within the concentration range of 0-7 mu M and the detection limit is 65 nM. In addition, the probe Cy-H2O2 has been successfully applied to H2O2 detection in living cells and zebrafish.

The selective hydrogenation of nitro compounds into their corresponding azo compounds is challenging in organic synthesis. In this study, we have developed a facile and efficient catalytic system for the transformation of nitro compounds into azo compounds under mild conditions over a heterogeneous cobalt catalyst (Co-N-x/C-800-AT). The Co-N-x/C-800-AT catalyst was found to be highly active for the reductive-coupling of nitro compounds into azo compounds in ethanol at 110 degrees C and 2.5 bar H-2 pressure with the addition of NaOH as an additive, affording structurally-diverse azo compounds with satisfactory yields (70.4-98.3%). The developed method demonstrated several advantages such as high catalytic activity and high selectivity with tolerance to other functional groups and high stability.

A convenient access toward novel fluoroionophores based on 1-(2-pyridyl)-4-styrylpyrazoles (PSPs) substituted at position 3 with donor or acceptor aryl groups is reported. The synthesis proceeds in two steps: the first one via Wittig olefination of the appropriate 4-formylpyrazole and then Mizoroki-Heck coupling to yield the desired products in an overall yield of up to 69%. Photophysical properties of products (4-styryl) and their intermediates (4-vinyl) were explored, finding that they have strong blue-light emission with high quantum yields (up to 66%) due to ICT phenomena. The 3-phenyl PSP was studied as a turn-off fluorescent probe in metal ion sensing, finding a high selectivity to Hg2+ (LOD = 3.1 x 10(-7)M) in a process that could be reversed with ethylenediamine. The sensing mechanism and binding mode of the ligand to Hg2+ were established by HRMS analysis and H-1 NMR titration tests.

Asymmetric catalysis with readily available, cheap, and non-toxic alkaline earth metal catalysts represents a sustainable alternative to conventional synthesis methodologies. In this context, we describe the development of a first Mg-II-catalyzed enantioselective hydroboration providing the products with excellent yields and enantioselectivities. NMR spectroscopy studies and DFT calculations provide insights into the reaction mechanism and the origin of the enantioselectivity which can be explained by a metal-ligand cooperative catalysis pathway involving a non-innocent ligand.

Zinc linked amino acid complex, Zn(l-proline)(2), is considered as a green catalyst for the synthesis of novel series of pyrimidine derivatives 5a-q. The pyrimidines 5a-q were prepared via two pathways: the first is a one-pot reaction of guanidines 3(a-c) with aromatic aldehyde 1 and acetophenones 2; and the second one is the reaction of guanidines 3(a-c) with different chalcones 4(a-j) in aqueous medium. The simplicity of the operation, the short reaction time, and the high efficiency (97%) are the main advantages of this protocol. Furthermore, the green aspects of this synthetic protocol were further investigated by examining the reusability of Zn(l-proline)(2) complex throughout five consecutive cycles without a significant loss of catalytic activity. This new procedure has presented remarkable advantages in terms of safety, simplicity, stability, mild conditions, a short reaction time, excellent yields, and high purities without using any organic solvents.

Substituted arylethylamines represent a key structural motif in natural, pharmaceutical, and agrochemical compounds. Access to such scaffolds has been the subject of long-standing synthetic interest. Herein, we report the synthesis of such scaffolds via a palladium-catalyzed C(sp(3))-C(sp(3)) coupling between (chloromethyl)aryls and air-/moisture-stable N,N-dialkylaminomethyltrifluoroborate salts. Rapid hit identification was achieved using microscale high-throughput experimentation and was followed by millimolar-scale reaction parameter optimization. A range of structurally and electronically varied arylethylamine products were obtained in moderate to excellent yields (27-96%, >60 examples). The reaction mechanism is proposed to proceed via formation of a trialkylbenzylammonium species prior to oxidative addition.
