We describe an efficient, clean and metal-free procedure for the synthesis of amides via oxidative amidation of aldehydes with anilines using graphene oxide (GO) as a recyclable catalyst and KBrO3 as a mild oxidant in aqueous medium under microwave irradiation. GO nanosheets were prepared and characterized by XRD, TEM, SEM, and FT-IR, analyses. GO showed high compatibility with KBrO3 in water and offered high TOF value (1.30 x 10(-3) mol g(-1) min(-1)). GO oxygen functionalities catalyze the oxidative amidation effectively in mild condition with high recyclability. A plausible mechanism was proposed by the isolating the intermediate.

The potent nucleophilicity and remarkably low basicity of 1,3,2-diazaphospholenes (DAPs) is exploited in a catalytic, metal-free 1,4-reduction of free alpha,beta-unsaturated carboxylic acids. Notably, the reduction occurs without a prior deprotonation of the carboxylic acid moiety and hence does not consume an additional hydride equivalent. This highlights the excellent nucleophilic character and low basicity of DAP-hydrides. Functional groups such as Cbz group or alkyl halides which can be problematic with classical transition-metal catalysts are well tolerated in the DAP-catalyzed process. Moreover, the transformation is characterized by a low catalyst loading, mild reaction conditions at ambient temperature as well as fast reaction times and high yields. The proof-of-principle for a catalytic enantioselective version is described.

We have investigated the stereoselective formation of spiro oxindole pyrrolidines via formal [3+2] cycloaddition of oxindole imines with ketoesters and ketoamides. Bifunctional squaramide organocatalyst was able to induce enantioselectivity of up to 60 % ee, increased to 72 % ee after re-crystallization, in the formation of spiro pyrrolidines with ketoesters. Interestingly, ketoamides provided alternative spiro oxindole pyrrole products in addition to the main product, which was formed via a different reaction pathway. Structures of spiro oxindole pyrrolidine as well as pyrrole products were confirmed by X-ray crystallographic analysis. Two new squaramide based catalysts were synthesized and tested. DFT calculation helped elucidate the reaction course.

Hydrogen sulfide (H2S) is a critical gasotransmitter playing an important role in various physiological and pathological processes. The development of fluorescent probes for rapid, sensitive, and selective lysosomal H2S sensing has attracted much attention. Herein we report a rhodamine based probe MF-N-3 that can selectively accumulate in lysosomes and give turn-on fluorescence in the presence of both H2S and protons. Results show that MF-N-3 has an exclusive response to H2S in the acidic lysosomal environment but does not respond in other organelles or in neutral environments. This strategy can circumvent the fluorescence interference from H2S of other sources, thus providing a high sensitivity and selectivity on lysosomal H2S imaging by fluorescence microscopy. This pH-dependent lysosome-targeting fluorescent probe has been successfully applied to lysosomal H2S imaging in living cells and is of great potential for applications to the environmental and biological systems.

An adequate enhancement in the development of resistance by microbial pathogens against the available chemotherapeutic agents prompted us to find out some new chemotherapeutic agents with significant therapeutic effect as antimicrobials. The present study reported the designing of 6-(1H-indol-3-yl)-4,5 ‘-bipyrimidine-2-amine (2) and its Schiff’s bases (3-12), and the computational studies were performed to assess properties (drug likeness and physicochemical). The computationally bioactive compounds (1-12) were then followed for synthesis, characterization, antimicrobial therapeutic effect and percent viability of cells. The antimicrobial therapeutic effect was obtained by disk diffusion method, in terms of zone of inhibition and minimum inhibitory concentration against the gram-positive and gram-negative bacteria [S. aureus (ATCC-25923), S. epidermidis (ATCC-29887)], [E. coli (ATCC-25922), P. mirabilis (ATCC-25933)]. The antimicrobial screening findings reveled that all the compounds (1-12) possessed very good activity and strongly recommended the computational results. The antibiotic ciprofloxacin and the solvent DMSO were used as positive and negative control in the study. The percent viability of the cells was observed using HepG2 cells by MTT assay and noticed that the percent viability of the cells was found in the range 93-97% at lowest concentration 3.125 mu M while 73-77% at the highest 100 mu M. All the compounds (1-12) and ciprofloxacin were then applied for molecular docking assessment to estimate the H-bonding with the residues of GlcN-6-P-synthase, and the findings revealed that significant H-bonding was observed with the binding affinity in the range of – 8.4 to 6.7 kcal/mol and – 7.6 to 6.0 kcal/mol, respectively.

All the four compounds were characterized by single-crystal X-ray diffraction, powder X-ray diffraction (XRD), IR spectroscopy, thermogravimetric analysis (TGA), and X-ray photoelectron spectroscopy (XPS). These compounds can serve as efficient heterogeneous catalysts for the cyanosilylation of different carbonyl compounds under ambient temperature and solvent-free conditions, and Cu-POM shows much better catalytic performance than the other three compounds. The cycle experiment showed that Cu-POM can be reused for at least five cycles without significant loss of catalytic activity. The IR spectroscopy and XRD analysis revealed that Cu-POM can retain its integrity after catalysis.

The radiation-induced reactions of ligands play an important role in the sensitization of metal oxide nanocluster resists. However, the details in the radiation chemistry of ligands for metal oxide nanocluster resists are still unknown. In this study, the radiation-induced reactions of carboxylic acid ligands were investigated using a pulse radiolysis method. The rate constants for the reactions of molecular and ionic forms of tiglic, angelic, o-toluic, and p-toluic acids with hydrated electrons were determined. The rate constants for the reactions of tiglic, angelic, benzoic, o-toluic, and p-toluic acids with dodecane radical cations were also determined. The radical ions of tiglic and angelic acids were more unstable than those of benzoic, o-toluic, and p-toluic acids. The results obtained in this study indicate that the molecular structures of ligands affect their reactivity to cationic and anion species and the stability of their radical cations and anions.
