Sulfuric acid and aromatic compounds are abundant in the atmosphere and play an important role in aerosol nucleation and growth. The main objective of this work is to provide molecular level description of pre-nucleation clusters formed by these species. Our approach is based on size- and compositionselective generation of anionic clusters, consisting of sulfuric acid and series of aromatic carboxylates (ArCOO-; Ar =Phenyl, o-, m-, and p-CH3C6H4 ), and their subsequent characterization using photoelectron spectroscopy and quantum chemical calculations. The photoelectron spectra show that formation of these clusters is accompanied by a significant increase of electron binding energies, implying significant stabilization gained from electron delocalization upon complexation. Comparison between the experimental and calculated results suggests that under low temperature conditions these clusters behave more like a complex of sulfuric acid and aromatic carboxylate, (H2SO4)(ArCOO-), despite the fact that ArCOO- has much higher proton affinity than HSO4-. Similar result has been previously reported for sulfuric acid formate cluster [Hou, Wang, and Valiev, J. Am. Chem. Soc. 139 (2017) 11321-11324], and indicates that interaction energy gained though the formation of these clusters is sufficient to counteract proton affinity imbalance. The calculated intermolecular binding energies (BEs), Gibbs free energies (Delta G), and evaporation rates (gamma) show that these (H2SO4)(ArCOO- ) clusters are extremely stable, with BEs of similar to 54 kcal/mol, Delta G of similar to-40 kcal/mol, and gamma of 10(-20) s(-1) . The experimental and computational results reported in this work suggest that aromatic acids may play a significant role in facilitating the early stages of sulfuric acid nucleation.

A series of 30 small hybrid molecules are synthesized inspired from Combretastatin A-4 (CA-4), where ethylene-bridge of CA-4 is replaced with two five-membered heterocyclic rings, viz. isoxazoline and 1, 2, 3-triazole. These are joined by a methylene linker, with substitutions at A and B – ring position of CA-4. The new molecular entities have shown significant cytotoxicity to cancer cell from the IC(50)0.49 mu M-3.17 mu M with 1-((4,5-Dihydro-3-(2,5-dimethoxyphenyl)isoxazol-5-yl)methyl)-4-(4-methoxyphenyl)-1H-1,2,3-triazole displayed IC(50)0.422 +/- 0.07 mu M for A-549 -lung cancer cell line and IC(50)0.498 +/- 0.03 mu M for MDA-MB-231-breast cancer cell line. The western blot analysis, confocal staining and also byin vitrotubulin polymerization assay established the target specificity of the molecules as a tubulin polymerization inhibitor. Molecular docking & Molecular dynamics studies confirmed the binding interaction patterns of these molecules at the Colchicine binding site of tubulin and have correlated the observed experimental result with variation in structure satisfactorily.

A simple and efficient cascade reaction via formal [1+2+3] cyclization of 1,3-indanedione, aldehyde and 2-naphthol is reported using K2CO3 as a base. The advantage includes metal-free conditions, varied substrate scope and shortened reaction duration with high diastereoselectivity (i. e., 99 : 1) resulting in the formation of two carbon-carbon as well as two carbon-oxygen bonds through Knoevenagel-Friedel-Crafts-Hemiketalization sequence resulting in three contiguous stereocenters.

Here we describe the development of biaryl 2,5-diphenylphospholanes as a new class of C-2-symmetric, monodentate ligands for asymmetric Suzuki-Miyaura (ASM) reactions. Screening of a series of exemplary phospholanes led to the identification of two ligands that were used to prepare a range of atropisomeric biaryl and heterobiaryl products with good to excellent levels of enantioselectivity (up to 97:3 e.r.) under mild conditions. DFT studies suggest that the formation of a constraining ligand pocket and coordination of one of the biaryl methoxy groups in the optimised ligands to the metal centre is crucial for restricting conformational freedom in the bond-forming step.

A nondirected amidation reaction of aromatic C-H bond was developed under iron(II) catalysis, using sulfonyl azides as the nitrogen source. The reaction displayed a broad substrate scope and good regioselectivities in the aspects of aromatic ring vs alkyl chain and different aromatic position of (alkyl)arenes. This method provided a new protocol for the synthesis of some aromatic amines, which were hard to achieve in a previous report.

The chemical composition of essential oils (EOs) isolated by hydrodistillation from Pterocarpus soyauxii Taub. root wood and root bark were determined for the first time by GC/MS analysis. The EOs gave a percentage yield (w/w) of 0.34 % and 0.31 % for root wood and root bark respectively. A total of 60 compounds accounting for 86.1 % of the root wood EO composition were identified with monoterpenes (45.4 %) and sesquiterpenes (14.7 %) as predominant constituents. Root bark EO gave 53 identified constituents which make up about 78.5 % of the EO dominated by non-terpenes (23.4 %) and alkanes (14.1 %). The EOs are good sources of limonene (16.9 %), gamma-terpinene (9.8 %) and p-cymene (6.70 %). The anti-diabetic (alpha-amylase and alpha-glucosidase models) and antioxidant activities (DPPH and H2O2 models) of EOs were evaluated in comparison with standard drugs. Alpha-amylase inhibition gave IC50 values (mg/mL) of 0.0493 and 0.0471 for root wood and root bark EOs respectively, compared to acarbose the standard anti-diabetic drug (0.0401) while alpha-glucosidase assay gave IC50 values (mg/mL) of 0.0517 and 0.0486 for root wood and root bark EOs respectively, compared with acarbose (0.0418). In the DPPH antioxidant assay, root bark EO showed higher activity (0.157 mg/mL) compared to root wood EO (0.159 mg/mL) while Root wood and root bark EOs had IC(50 )values (mg/mL) of 0.157 and 0.171 respectively using the H2O2 model. Results revealed the presence of chemical constituents in the EOs which could be responsible for activities expressed by the plant.

Metal-free Friedel-Crafts benzylation (FCB) of scarcely reactive arenes and heteroarenes was performed under on-water conditions by an environmentally sustainable procedure. The catalytic strategy exploits the hydrophobicity of the resorcinarene macrocycle 1 a. The proposed mechanism is based on the activation of benzyl chloride by H-bonding interactions with catalyst 1 a. In fact, under on-water conditions the hydrophobic amplification of the strength of the H-bonding interactions between the OH groups of the resorcinarene catalyst and the chlorine atom of benzyl chloride leads to polarization of the C-Cl bond, which consequently promotes electrophilic attack of the pi nucleophile. Thus, many arenes and heteroarenes were efficiently benzylated under mild on-water conditions by using resorcinarene 1 a as catalyst. The FCB of benzene is industrially relevant for the synthesis of diphenylmethane, and hence the on-water procedure was extended to the gram-scale synthesis of diphenylmethane, starting from benzene and benzyl chloride in the presence of resorcinarene catalyst 1 a.

A diverse range of ureas, N-acylureas, carbamates, and thiocarbamates has been synthesized in good to excellent yields by reacting N-acylbenzotriazoles individually with amines or amides or phenols or thiols in the presence of diphenylphosphoryl azide (DPPA) as a suitable azide donor in anhydrous toluene at 110 degrees C for 3-4 hours. In this route, DPPA was found to be a good alternative to trimethylsilyl azide and sodium azide for the azide donor in Curtius degradation. The high reaction yields, one-pot and metal-free conditions, straightforward nature, easy handling, use of readily available reagents, and in many cases avoidance of column chromatography are the notable features of the devised protocol.

A bifunctional amine/squaramide catalyst promoted direct aldol addition of an hydantoin surrogate to pyridine 2-carbaldehyde N-oxides to afford adducts bearing two vicinal tertiary/quaternary carbons in high diastereo- and enantioselectivity (d.r. up to >20:1; ee up to 98 %) is reported. Acid hydrolysis of adducts followed by reduction of the N-oxide group yields enantiopure carbinol-tethered quaternary hydantoin-azaarene conjugates with densely functionalized skeletons. DFT studies of the potential energy surface (B3LYP/6-31+G(d)+CPCM (dichloromethane)) of the reaction correlate the activity of different catalysts and support an intramolecular hydrogen-bond-assisted activation of the squaramide moiety in the transition state of the catalytic reaction.
