Transition-metal-catalyzed sp(2) C-N bond formation is a reliable method for the synthesis of aryl amines. Catalytic sp(3) C-N formation reactions have been reported occasionally, and methods that can realize both sp(2) and sp(3) C-N formation are relatively unexplored. Herein, we address this challenge with a method of catalytic decarboxylative C-N formation that proceeds through a cascade carboxylic acid activation, acyl azide formation, Curtius rearrangement and nucleophilic addition reaction. The reaction uses naturally abundant organic carboxylic acids as carbon sources, readily prepared azidoformates as the nitrogen sources, and 4-dimethylaminopyridine (DMAP) and Cu(OAc)(2) as catalysts with as low as 0.1 mol % loading, providing protected alkyl, alkenyl and aryl amines in high yields with gaseous N-2 and CO2 as the only byproducts. Examples are demonstrated of the late-stage functionalization of natural products and drug molecules, stereospecific synthesis of useful alpha-chiral alkyl amines, and rapid construction of different ureas and primary amines.

The electronic structure and electronic transitions of four new mono Schiff base derivatives are interpreted by using absorption and fluorescence spectra including 28 different solution medium. Electrical dipole moments have been found by means of four different quantum mechanical methods based on solvatochromic shifts like Lippert-Mataga, Bakhshiev, modified Bilot-Kawski, and Reichardt methods. Quantitative researches of solvent-solute interactions are done by using Kamlet-Taft and Catalan parameters. In absorption and fluorescence spectra, bathochromic shift occurs with dispersion-polarization forces effect. The electronic transitions and electronic structure of these molecules have changed to dependent on solvent medium property. HOMO, LUMO, MEP, and SAS were calculated using B3LYP/6-311G(d,p) level of theory. Solvatochromism, photophysical properties, and electronic structure were discussed in detail. The dipole moments in ground-state and excited-state have not almost change.

A new metal-, oxidant-, and solvent-free ecofriendly domino method has been established for modular synthesis of a diverse range of medicinally promising hydroxyarylated unsymmetrical pyridines in good to high chemical yields with an excellent regioselectivity. This domino process involves a range of N-sulfonyl ketimines as C,N-binucleophiles, enolizable ketones, and aromatic/heteroaromatic aldehydes using ammonium acetate as an ideal promoter under neat conditions, which creates two new C-C bonds and one C-N bond. Notably, the neutral reaction conditions are mild enough to tolerate a range of functionalities and cover a variety of substrates, thus bestowing a powerful avenue to access tri- and tetrasubstituted pyridines including carbo- and heterocyclic fused ones. Interestingly, a practical, scalable, and high-yielding synthesis of pyridylphenol derivatives was successfully accomplished by our unique method.

Saw the article Scalable Multicomponent Synthesis of (Hetero)aryl-Substituted Phenyls: Focus on Metal-Free Halogenated Biaryls, 3-Arylindoles, and Isourolithine A Synthesis published in 2019.0, Reprint Addresses Temperini, A (corresponding author), Univ Perugia, Dipartimento Sci Farmaceut, Via Liceo 1, I-06123 Perugia, Italy..

In the context of the growing interest of the scientific community for the development of sustainable synthetic strategies to access aromatic structures, we present a practical and metal-free approach to (hetero)biaryls which exploits the advantages of multicomponent reactions in sustainable solvents. In situ acid-catalysed generation of (hetero)aryl acetoxy dienes from the corresponding (hetero)arylidene acetones in a metal vessel, followed by Diels-Alder reaction using an electron-poor alkyne as dienophile, delivers the expected aromatic products after final oxidation of the cycloadduct. This protocol has been demonstrated as a convenient alternative to the previously reported synthetic strategies, considering its scalability and environmental sustainability and the low cost of substrates and equipment. Moreover, it has been successfully applied to the metal-free regioselective synthesis of (hetero)aryl-substituted-phenyls, 2-unsubstituted-3-aryl-indoles, and to the total synthesis of isourolithine A.

A genetically encoded fluorescent tag for live cell microscopy is presented. This tag is composed of previously published fluorogen-activating protein FAST and a novel fluorogenic derivative of green fluorescent protein (GFP)-like chromophore with red fluorescence. The reversible binding of the novel fluorogen and FAST is accompanied by three orders of magnitude increase in red fluorescence (580-650 nm). The proposed dye instantly stains target cellular proteins fused with FAST, washes out in a minute timescale, and exhibits higher photostability of the fluorescence signal in confocal and widefield microscopy, in contrast with previously published fluorogen:FAST complexes.

Chalcone based structures have many interesting biological properties like anti-malarial, anticancer, antiviral, antibacterial, antifungal, anti-hyperglycaemic and photo-cytotoxicity activities. In this study, the novel chalcone derivatives (1a-11) have been synthesized and investigated for antimicrobial activities. The MIC results of antimicrobial activities reveal that one of the chalcone derivative (2-Br- and 4OCH(3)- group) against specific bacteria are quite significant. 3D QSAR, three dimensional quantitative structure activity is one of the most powerful technique which involves the quantitative relationship between the biological activity of a set of compounds and their three dimensional structural properties, using statistical correlation methods. Pharmacophore modelling and molecular docking play an important role in drug design. To elucidate the relationship between structures and its activity, field-based 3D QSAR analysis has been carried out of novel chalcone derivatives. Structural properties such as electrostatic, hydrophobic, aromatic, and hydrogen-bond donor and acceptor have been worked out for novel chalcone derivatives. To investigate the influence of drugstore, chalcone derivatives (1a-11) have docked with receptor 210K and results displayed the highest Gscore of ligand If (3-OCH2C6H5-4-OCH3- group).
