Development of tunable photonic devices having molecular dimensions is an active research area in nonlinear optics which continues to evolve and impact many technologies. Here, we demonstrate the tailoring of nonlinear optical properties of nitrochalcone derivatives by engineering the donor-acceptor configurations on either end of the molecules, to control the intramolecular charge transfer process. The central pi-bridge in chalcones provides delocalized electrons which lead to the nonlinear polarizability observed in these molecules. Optical nonlinearity is studied by means of second harmonic generation (SHG) and open aperture Z-scan measurements. Samples show optical limiting behaviour in the nanosecond excitation regime due to excited state absorption (ESA) and two-photon absorption (2PA) phenomena. Our study highlights the importance of structure-property correlations in molecular designs.

Concerns regarding animal welfare have led to the need for alternatives to animal eye irritation tests. The reconstructed human cornea-like epithelium (RhCE) test is described in the OECD TG 492 as an alternative to animal eye irritation tests. However, the accuracy and labor investment of this method can be improved if the results can be predicted before the experiment. In this study, we evaluated whether Hansen solubility parameter (HSP) values can be used to predict the results of RhCE method using the LabCyte CORNEA-MODEL for 65 test substances. We found that HSP values can predict the RhCE method with high correlation (accuracy 84.6% (55/65), false-negative rate of 16.2% (7/43), and false-positive rate of 13.6% (3/22). These results indicate that HSP values can be used to predict the results RhCE method using LabCyte CORNEA-MODEL with high reproducibility, and thus are useful for evaluating the safety of substances.

An urgent yet challenging task is to overcome the limitations in substrate scope and regio- and chemoselectivity in the oxidative couplings between two arenes for the construction of unsymmetrical 2,2′-difunctional biaryls with diverse application requirements. In this work, a co-oxidant-free Rh(I)/Zn(NTf2)(2)/air catalytic system has been developed for dual chelation-assisted oxidative C-H/C-H cross-couplings between two anilines, between two phenols, and between phenols and anilines, which enables rapid assembly of rich libraries of 2,2′-bianilines, 2,2′-biphenols, and 2′-aminobiphenyl-2-ols. This protocol features air as the sole oxidant, complete regioselectivity, high chemoselectivity, low molar ratio of substrates (even 1:1), convenient operation, and scale-up synthesis. The established catalytic system is tolerant of the substrates having both electron-donating and electron-withdrawing substituents at different positions of the aryl ring. This work further discloses that the chemoselectivity of cross-coupling over homocoupling mainly relies on a suitable combination of two directing groups (i.e., a pair of strongly and weakly coordinating directing groups) rather than the electronically distinct properties between two substrates, which provides an inspiration for designing the matching directing group pair for the dual chelation-assisted oxidative Ar-H/Ar-H cross-couplings. Thus, this strategy allows the highly chemoselective cross-coupling between electronically similar coupling partners, which represents a challenging task in the oxidative Ar-H/Ar-H cross-coupling reactions.

In the present investigation, a series of dihydrotriazine derivatives-bearing 5-aryloxypyrazole moieties were synthesized and their structures were confirmed by different spectral tools. The biological evaluation in vitro revealed that some of the target compounds exerted good antibacterial and antifungal activity in comparison with the reference drugs. Among these novel hybrids, compound 10d showed the most potent activity with minimum inhibitory concentration values (MIC) of 0.5 mu g/mL againstS. aureus4220, MRSA 3506 and E. coli 1924 strain. The cytotoxic activity of the compounds 6d, 6m,10d and 10g was assessed in MCF-7 and HeLa cells. Growth kinetics study showed significant inhibition of bacterial growth when treated with different conc. of 10d. In vitro enzyme study implied that compound 10d exerted its antibacterial activity through DHFR inhibition. Moreover, significant inhibition of biofilm formation was observed in bacterial cells treated with MIC conc. of 10d as visualized by SEM micrographs. [GRAPHICS] .

The competition between an unprecedented reductive chlorination and the Pummerer reaction was studied and applied to the synthesis of benzofused oxygen heterocycles including 3-aminochromanes and in the intramolecular chlorination of activated aromatic rings. The use of (COCl)(2) as a Pummerer activator showed substantial activity, producing alpha-chlorinated sulfides that can undergo Pummerer-Friedel-Crafts cyclization. If the aromatic ring has electron-donating groups in position three, then the reaction follows a different pathway, yielding the reductive chlorination products, where the chlorine atom comes from a sulfonium salt.

An efficient synthesis of 4-arylidene-3-alkylisoxazole-5(4H)-ones has been implemented via the three-component cyclocondensation of aryl(heteroaryl)aldehydes with hydroxylamine hydrochloride and beta-ketoesters. The potassium 2,5-dioxoimidazolidin-1-ide has been introduced as the new organocatalyst to facilitate this heterocyclization. In the current process, three starting materials, including substituted benzaldehydes/heterocyclic aromatic aldehydes, hydroxylamine hydrochloride, and ethyl acetoacetate/propyl acetoacetate/butyryl acetoacetate have been successfully used to synthesize the number of substituted isoxazole-5-(4H)-ones in good to high yields in ethylene glycol as a green reaction medium at 80 degrees C. The low catalyst loading is also a main advantage over some reported catalysts.

A new recyclable nanocatalyst consisting of heteropoly acid grafted on ionic liquid modified LaMnO3 nanoparticles was synthesized and accomplished as an efficient catalyst in condensation reaction for the preparation of tetrahydrobenzo[b]pyrans under solvent-free conditions. In addition, it was clarified that supported heteropoly acid (HPA) is the active site for the catalytic reaction, whereas the LaMnO3, ionic liquid functionalized lanthanum manganite nanoparticles are inactive. Different physicochemical methods such as Fourier transform infrared (FT-IR), X-ray powder diffraction (XRD), and field emission scanning electron microscopy (FESEM) were used to characterize the hybrid nanomaterial. The nanocatalyst reusability was affirmed by the use of five consecutive runs. Compared with the various previously reported catalyst, the new synthesized catalyst was found to be the most efficient with regard to reaction time, yield and ease of catalyst separation.

The Pot, Atom, and Step Economy (PASE) approach is based on the Pot economy principle and unites it with the Atom and Step Economy strategies; it ensures high efficiency, simplicity and low waste formation. The PASE approach is widely used in multicomponent chemistry. This approach was adopted for the synthesis of previously unknown hydroxyquinolinone substituted chromeno[2,3-b]pyridines via reaction of salicylaldehydes, malononitrile dimer and hydroxyquinolinone. It was shown that an ethanol-pyridine combination is more beneficial than other inorganic or organic catalysts. Quantum chemical studies showed that chromeno[2,3-b]pyridines has potential for corrosion inhibition. Real time H-1 NMR monitoring was used for the investigation of reaction mechanism and 2-((2H-chromen-3-yl)methylene)malononitrile was defined as a key intermediate in the reaction.
