Catalytic asymmetric cycloadditions via transition-metal-containing dipolar intermediates are a powerful tool for synthesizing chiral heterocycles. However, within the field of palladium catalysis, compared with the well-developed normal electron-demand cycloadditions with electrophilic dipolarophiles, a general strategy for inverse electron-demand ones with nucleophilic dipolarophiles remains elusive, due to the inherent linear selectivity in the key palladium-catalyzed intermolecular allylations. Herein, based on the switched regioselectivity of iridium-catalyzed allylations, we achieved two asymmetric [4+2] cycloadditions of vinyl aminoalcohols with aldehydes and beta,gamma-unsaturated ketones through synergetic iridium and amine catalysis. The activation of vinyl aminoalcohols by iridium catalysts and carbonyls by amine catalysts provide a foundation for the subsequent asymmetric [4+2] cycloadditions of the resulting iridium-containing 1,4-dipoles and (di)enamine dipolarophiles. The former provides a straightforward route to a diverse set of enantio-enriched hydroquinolines bearing chiral quaternary stereocenters, and the later represent an enantio- and diastereodivergent synthesis of chiral hydroquinolines.

A general synthesis of chiral alpha,alpha-diaryl carboxamides is developed by enantioselective cross-coupling between 2-bromo-2-aryl carboxamides and arylboronic acids, leading to a series of chiral alpha,alpha-diaryl carboxamides with various electronic properties and functionalities in moderate to excellent enantioselectivities and yields. The employment of a sterically bulky chiral P,P=O ligand L2 is critical for the reactivity and selectivity. This protocol is applied to an efficient asymmetric synthesis of a key intermediate of dopamine receptor agonist SKF 38393.

To explore new skeleton with nematicidal activity, a series of novel 1,2,3-benzotriazin-4-one derivatives containing piperazine as linker were synthesized and varied fragments were also introduced to increase structure diversity of the new skeleton. Their inhibitory activities in vivo were evaluated against Meloidogyne incognita. The newly prepared compounds A6, A8, A21, A28 and A38 exhibited more than 50% inhibition at the concentration of 20 mg/L. Especially compound A6 displayed 71.4% inhibition against Meloidogyne incognita at the concentration of 20 mg/L. The nematicidal activities varied significantly depending on the types and positions of the substituents, which provided guidance for further structure modification.

Insect-microbial symbioses have vast biochemical diversity, which is beneficial to produce bioactive secondary metabolites. In this study, chemical examination of a Streptomyces sp. associated with a mud dauber wasp led to the isolation of fourteen compounds. Their structures were determined by spectroscopic methods and comparison with literature data. Among the isolates, compounds 1,2,3-benzotriazin-4(1H)-one and 4-(2-aminoethyl)phenyl acetate were first reported from this species. Bioactivities of the isolated compounds were assayed for the first time against hexokinase II. 4-(2-Aminoethyl)phenyl acetate, germicidin B, phenylacetic acid, isogermicidin A and germicidin C displayed significant inhibitory activity against hexokinase II, with the IC50 values of 5.11, 7.11, 7.15, 8.45 and 8.78 mu M, respectively.

Metal-free, visible-light-induced denitrogenative phosphorylation of 1,2,3-benzotriazinones was achieved. With the use of eosin Y as a photoredox catalyst, N,N-diisopropylethylamine as a base, CH3CN-H2O as a solvent and sunlight or a blue LED as a light source, a variety of aryl-phosphonates, aryl-phosphinates, and aryl-phosphine oxides were efficiently prepared. In addition, B(2)pin(2) instead of P-nucleophiles as a radical acceptor was also demonstrated. The key advantages of this newly developed method are the clean reaction profile, use of a low-cost organic-dye catalyst, energy efficiency, broad substrate scope, good to excellent yields and large-scale synthetic applicability. The gram-scale synthesised compounds could be isolated in pure form just upon extraction, followed by re-crystallisation; no tedious chromatographic purification was required.

The design of surface-enhanced Raman spectroscopy (SERS) platforms based on the coupling between plasmonic nanostructures and stimuli-responsive polymers has attracted considerable interest over the past decades for the detection of a wide range of analytes, including pollutants and biological molecules. However, the SERS intensity of analytes trapped inside smart hybrid nanoplatforms is subject to important fluctuations because of the spatial and spectral variation of the plasmonic near-field enhancement (i.e., its dependence with the distance to the nanoparticle surface and with the localized surface plasmon resonance). Such fluctuations may impair interpretation and quantification in sensing devices. In this paper, we investigate the influence of the plasmonic near-field profile upon the Raman signal intensity of analytes trapped inside thermoresponsive polymer-coated gold nanoarrays. For this, well-defined plasmonic arrays (nanosquares and nanocylinders) were modified by poly(N-isopropylacrylamide) (PNIPAM) brushes using surface-initiated atom-transfer radical polymerization. Molecular probes were trapped inside these Au@PNIPAM nanostructures by simple physisorption or by covalent grafting at the end of PNIPAM brushes, using click chemistry. The SERS spectra of molecular probes were studied along various heating/cooling cycles, demonstrating a strong correlation between SERS intensities and near-field spectral profile of underlying nanoparticles, as confirmed by simulations based on the finite difference time domain method. Thermoresponsive plasmonic devices thus provide an ideal dynamic SERS platform to investigate the influence of the near-field plasmonic profile upon the SERS response of analytes.

A novel easy-to-prepare magnetic catalyst, composed of palladium nanoparticles supported on surface-oxidized carbon-encapsulated iron nanoparticles, has been synthesized. The synthesis involved the reduction of palladium precursor in the presence of magnetic core-shell nanomaterial. The size of the palladium nanoparticles distributed over the support does not exceed 15 nm. The catalytic performance of this composite material was tested in hydrogenation of seven various nitro compounds to the respective amino derivatives. The composite exhibits excellent catalytic activity and can be easily separated from the reaction mixture after the reaction. The determined reaction yields were above 90 % and this value was not worsened even after ten cycles, for the case of hydrogenation of nitrobenzene. Importantly, the method is chromatography-free and employs the ammonium formate as a hydrogen source, which makes the herein presented protocol safer in comparison with the previously reported reductions in which highly dangerous gaseous hydrogen was used.
