A catalytic annulation cascade is achieved that affords an efficient access to phthalides from readily available benzoic acids and saturated ketones. The reaction is catalyzed by a bimetallic Ir/Cu system and proceeds via the combination of Cu-catalyzed dehydrogenation of ketones and Ir-catalyzed direct C-H functionalization under the assistance of the weakly coordinating carboxyl followed by the beta-H elimination and intramolecular Michael addition. This method shows a broad scope of substrates and good functional group tolerance. The protocol furnishes an alternative strategy for the construction of diverse 3-substituted phthalides.

Competitive reactions, on the surface of plasmonic nanostructures, allow exploiting SERS signals for quantitative Therapeutic Drug Monitoring. As an example, the concentration of Erlotinib, an anti-EGFR small molecule, used for the treatment of non-small cell lung and pancreatic cancer, is determined. The numerous side effects and the variability of patient responses make Erlotinib a good candidate for monitoring. The new SERS based sensor can estimate Erlotinib down to nanomolar concentration and is based on the chemical reaction of the drug and of a competitor SERS reporter on the surface of gold nanostructures. Colloid solutions of naked gold nanoparticles obtained by laser ablation in solution were used for obtaining nanostructures with very efficient hot spots for SERS and with a clean surface for chemistry. Detection of the drug in the nanomolar concentration range is shown to be possible also in spiked plasma samples. (C) 2018 Elsevier Inc. All rights reserved.

Timely myocardial reperfusion salvages ischemic myocardium from infarction, whereas reperfusion itself induces cardiomyocyte death, which is called myocardial ischemia/reperfusion (MI/R) injury. Herein, beta-carboline derivative 17c was designed and synthesized with obvious myocardial protective activity for the first time. Pretreatment of 17c effectively protected the cardiomyocyte H9c2 cells from H2O2-induced lactate dehydrogenase leakage and restored the endogenous antioxidants, superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px). Besides, 17c effectively protected the mitochondria through decreasing the reactive oxygen species overproduction and enhancing the mitochondrial membrane potential. As a result, 17c significantly reduced the necrosis of cardiomyocytes in H2O2-induced oxidative stress, which was more potent than polydatin. In MI/R injury rats, 17c pretreatment obviously increased the levels of SOD and GSH-Px and inhibited the apoptosis of cardiomyocytes. Through this way, the size of myocardial infarction was significantly reduced after MI/R injury in vivo, better than that of polydatin, suggesting that 17c is a promising cardioprotectant for the prevention of MI/R injury.

A series of substituted benzoate-bridged dichromium(II, II) complexes [Cr-2(RCO2)(4)(THF)(2)] ([Cr-2]), where RCO2- is substituted benzoate, was synthesized and its structural and magnetic properties were investigated. The orbital energies, as well as magnetic coupling energies, were also investigated using computational approaches. The HOMO/LUMO energy levels of the complexes are strongly dependent on the acidity, i.e., pK(a), of the corresponding benzoic acids (RCO2H), revealing a linear trend in the respective groups of non-ortho, mono-ortho, and bi-ortho substituted groups. The Cr center dot center dot center dot Cr magnetic coupling constant (E-S (T)) is little affected by pK(a); instead, the E-S (T) is associated with the HOMO/LUMO gap and strongly correlated with the Cr center dot center dot center dot Cr distance.

We present a computational study of polarizabilities and hyperpolarizabilities of organic molecules in aqueous solutions, focusing on solute-water interactions and the way they affect a molecule’s linear and non-linear electric response properties. We employ a polarizable quantum mechanics/molecular mechanics (QM/MM) computational model that treats the solute at the QM level while the solvent is treated classically using a force field that includes polarizable charges and dipoles, which dynamically respond to the solute’s quantum-mechanical electron density. Quantum confinement effects are also treated by means of a recently implemented method that endows solvent molecules with a parametric electron density, which exerts Pauli repulsion forces upon the solute. By applying the method to a set of aromatic molecules in solution we show that, for both polarizabilities and first hyperpolarizabilities, observed solution values are the result of a delicate balance between electrostatics, hydrogen-bonding, and non-electrostatic solute solvent interactions.

The extensively developed ene-type enantioselective cycloisomerization of classical 1,n-enynes provides an efficient approach to chiral cyclic 1,4-dienes. In contrast, the catalytic asymmetric heteroarenyne (heteroarene-alkyne) cycloisomerization involving the dearomative transformation of endocyclic aromatic C=C bonds remains unknown. Herein, we communicate a PdH-catalyzed enantioselective heteroarenyne cycloisomerization reaction of alkyne-tethered indole substrates (formal 1,5- and 1,6-enynes). Based on this strategy, a variety of structurally diverse chiral spiro and fused indoline derivatives bearing quaternary stereocenters and exocyclic C=C bonds are afforded in moderate to excellent yields and excellent enantioselectivities (up to 98 % ee). The classical ene-type enantioselective 1,5-enyne cycloisomerization of N-vinylpropiolamides is also developed to afford chiral 2-pyrrolones in good to excellent ee values.

Through topology-guided synthesis, a Zr-based mesoporous MOF was successfully constructed, adopting a b-cristobalite-type structure. The MOF is embedded with well-arranged terpyridine coordination sites for facile post-syntheticmetalation, and can be effectively used as a general scaffold for the preparation of noble-metal-free catalysts. For instance, the scaffolded metal@MOF material exhibits highly efficient catalytic activity for alkene epoxidation and arene borylation.

We propose a new protocol for synthesis of the arylidene-1H-imidazol-5(4H)-ones which is based onO-alkylation of amidoacetates using triethyloxonium tetrafluoroborate leading to carboximidates. These imidates have long been used in the synthesis of imidazolones by [2+3] cycloaddition reaction with Schiff bases. However, diversity of carboximidates prepared by the common techniques was limited. The protocol we proposed eliminated these limitations. Using this technique, a number of derivatives of the green fluorescent protein (GFP) and asFP chromophores were synthesized, and influence of the C2 residue on their optical properties was studied.
