It is reported that cheap and easily available Hg(OTf)(2) can efficiently mediate the Sakurai-Hosomi reaction of N-tert-butyloxycarbonyl (Boc) amino sulfones, aldehydes, and alpha-fluoroalkyl ketones using allyltrimethylsilane, with the catalyst loading down to 0.5-5.0 mol%, enabling the facile access to synthetically valuable homoallylic alcohols or amines, respectively. A chemoselective 1,4-allylation of alpha,beta-unsaturated enones is also achieved under the catalysis of 5.0 mol% Hg(OTf)(2). In most cases, Hg(OTf)(2) exhibited intriguing properties superior to those of commonly used metal Lewis acids for such reactions, suggesting that mercury catalysis is worthwhile to explore.

An efficient and sustainable protocol for the hydration of alkynes has been developed under metal/acid/catalyst/ ligand-free conditions in a water/ethyl lactate mixture. The hydrogen-bond network in the ethyl lactate and water mixture plays a crucial and decisive role in activating the alkynes for hydration to afford the corresponding methyl ketones. This strategy gives the Markovnikov (ketone) addition product selectively over other possible products. The essential role of hydrogen bonding has been confirmed by experimental and theoretical techniques. A probable mechanism has been suggested by various control tests. The efficacy of the method has been further explored for the competent production of value-added alpha,beta-unsaturated carbonyl compounds through the reaction of aldehydes with alkynes as ketonic surrogates. The environmentally benign hydration method takes place under mild conditions, has broad functional-group compatibility, and uses the ethyl lactate/water (1:3) medium as a green alternative in the absence of any hazardous, harmful, or expensive substances.

The most red-shifted hemithioindigo photoswitches have been identified through systematic introduction of aryl units to a parent pyrrole hemithioindigo photoswitch. Increasing the size of the 5′-aryl substituent is ineffective at producing further redshifted chromophores. A second generation of 3′,5′-diarylated photoswitches which possess increased tunability is reported. Experimental and computational evidence indicates the 4′ position is electronically isolated from the bulk of the conjugated system. (C) 2019 Elsevier Ltd. All rights reserved.

The (Fmes)BH2 center dot SMe2 reagent (7) reacts sequentially with an acetylene and, e.g., xylylisonitrile in a convenient three-component reaction to give a series of unprecedented dihydro-1,3-azaborole derivatives 16. The tolane-derived example 16a was deprotonated and used as a ligand in organometallic chemistry. Compounds 16 served as the starting materials for the straightforward synthesis of various dihydro-1,3-azaborinine derivatives by treatment with an isonitrile. Several diaryldihydro-1,3 azaboroles showed interesting photophysical properties such as aggregation-induced emission and high fluorescence quantum yields.

Inspired by the synergistic effects of hetero-aromatic scaffolds on curcumin, a novel array of pyrazoline substituted curcumin analogs was designed. Multi-scale computational studies were carried out to target the proposed analogs on human kinase beta (IKK-beta), a potential anti-cancer target. In molecular docking analysis, all the eleven molecules were observed to bind the target site and 4-bromo-4′-chloro analog displayed three hydrogen bond interactions with a docking score of -11.534 kcal/mol higher than parent molecule, curcumin (docking score = -7.12 kcal/mol) as the propellant shaped of analogs aided in proper binding with Kinase Domain binding pocket. The molecular dynamics and simulations studies revealed that the stable complexes of lead molecule were developed as the minimal deviations per residue of protein found within the range of 0.11 to 0.92 angstrom. The proposed compounds were synthesized, characterized and biologically evaluated against human cervical cancer cell line, HeLa, using standard MTT cell assay. Bio-evaluation studies exhibited superior cytotoxic profile for many analogs as Chloro bromo analog with IC50 value (8.7 mu g/mL) exhibited fivefolds improvement in the potency in comparison to curcumin (IC50 = 42.4 mu g/mL) but was less potent than the standard drug, paclitaxel (IC50 = 0.008 mu g/mL). The apoptotic effect was evaluated in the terms of caspase-3 enzyme cleavage and exhibited 70.5% of apoptosis significantly (p < 0.05) higher than 19.9% induced by curcumin. In short, 4-bromo-4'-chloro analog was the potent cytotoxic agent in this structural class and must be evaluated further under a set of stringent parameters for transforming in to a clinically viable therapeutic molecule.

Plant viral diseases, known as plant cancer, with high contagiosity can substantially reduce crop quality and yield. To identify potential anti-tobacco mosaic virus (TMV) agents with different mechanisms, a series of novel alpha-aminophosphonate derivatives containing a chalcone moiety were designed and synthesized. Bioassay results revealed that some target compounds exhibited improved curative activity against TMV in vivo, and the EC50 value of compound B-3 was 356.7 mg L-1. The activities of the defensive enzymes POD and CAT from tobacco leaves treated with B-3 and B-17 showed that these target compounds could improve the photosynthetic ability of the leaves and activate plant host resistance against TMV infection. The binding constant between B-3 and TMV Coat Protein (CP) (2.51 x 10(8) M-1), calculated by the fluorescence titration experiment and docking results, revealed that B-3 has a strong interaction with TMV CP. Further docking analysis revealed that B-3 was embedded between two layers of the TMV CP, which was consistent with the 2:1 binding mode of TMV CP and B-3 determined by the binding affinity experiment. The TEM morphological study of TMV treated with B-3 and B-17 indicated that this series of target compounds may trigger the disassembly of TMV by interacting directly with TMV CP. This study provides new insight for the discovery of antiviral compounds with two different mechanisms of action.

The highly selective C = C reduction of alpha,beta-enones was realized by CF3SO3H-modifying noble-metal-free TiO2 photocatalysis. Selectivity for C = C over C = O reduction was dramatically reversed from fair (similar to 42% without CF3SO3H-modifying) to excellent (> 99%) upon only 6 mol% CF3SO3H loading without any noble-metal additive. Attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR) and C-13-nuclear magnetic resonance (NMR) demonstrated that CF3SO3H modification results in the alpha,beta-enone polar C = O bond sitting away from rather than near to the active sites of polar TiO2 catalysts.
