Application of Pinacolborane in Catalytic Enantioselective Hydroboration of Ketones and Imines

Enantioselective hydroboration of ketones and imines provides a powerful method to access valuable chiral alcohols and amines which are widely used in organic synthesis, materials science, pharmaceutical, agrochemistry and fine chemical industry. After invented in 1991, pinacolborane (HBpin) as a stable, commercially available and measurably simple reductive reagent has been widely applied in hydroboration of carbonyl derivatives, imines and nitriles and relevant mechanistic investigation. In the past 5 years, HBpin has also been employed for asymmetric catalytic hydroboration (CHB) to access chiral alcohols and amines. The enantioselective CHB reactions of ketones and imines using HBpin are outlined according to the classification of different catalysts, such as earth abundant transition metals, main group elements, and rare-earth metals.

Multicolor Activatable Raman Probes for Simultaneous Detection of Plural Enzyme Activities

Raman probes based on alkyne or nitrite tags hold promise for highly multiplexed imaging. However, sensing of enzyme activities with Raman probes is difficult because few mechanisms are available to modulate the vibrational response. Here we present a general strategy to prepare activatable Raman probes that show enhanced Raman signals due to electronic preresonance (EPR) upon reaction with enzymes under physiological conditions. We identified a xanthene derivative bearing a nitrile group at position 9 (9CN-JCP) as a suitable scaffold dye, and synthesized four types of activatable Raman probes, which are targeted to different enzymes (three aminopeptidases and a glycosidase) and tuned to different vibrational frequencies by isotope editing of the nitrile group. We validated the activation of the Raman signals of these probes by the target enzymes and succeeded in simultaneous imaging of the four enzyme activities in live cells. Different cell lines showed different patterns of these enzyme activities.

Clean and molecularly programmable protocol for preparation of bis-heterobiarylic systems via a domino pseudocyclic reaction as a valuable alternative for TM-catalyzed cross-couplings

The domino sequence of pseudocyclic reactions involving 4-methoxybenzonitrile N-oxide and trans-2-phenyl-1-cyano-1-nitroethene proceeding in mild (r.t.; atm. pressure) non-catalytic (without participation of palladium or other transition metals (TM)) conditions yielded a bis-heterobiarylic molecular system containing an oxadiazole moiety with an almost 40% yield. The presented methodology represents therefore an evident contrast to the existing methods of preparation of bis-heterobiarylic systems, which require the presence of TMs. This reaction should be considered stereochemically clean and contains a stage of cycloaddition to the C=N bond. It should be underlined that this is the first case of non-catalyzed [3 + 2] cycloaddition involving the nitrile C=N bond. Our comprehensive study shows that the described protocol can be applied as a general methodology for preparation of a wide group of bis-heterobiarylic molecules. The self-adjusted cascade of transformations, which is unique and valuable from the practical point of view, leads to formation of a single isomeric product (from many possible) as a consequence of three pseudocyclic tandem reactions performed in agreement with the fundamental principles of green chemistry and sustainable development with a maximal level of atom economy and good overall yields. A self-adjustment phenomenon observed in the studied smart technology leading to production of a material with special properties was explained by it deep quantum nature confirmed undoubtedly by the modern Molecular Electron Density Theory.

Ni2P Nanoalloy as an Air-Stable and Versatile Hydrogenation Catalyst in Water: P-Alloying Strategy for Designing Smart Catalysts

Non-noble metal-based hydrogenation catalysts have limited practical applications because they exhibit low activity, require harsh reaction conditions, and are unstable in air. To overcome these limitations, herein we propose the alloying of non-noble metal nanoparticles with phosphorus as a promising strategy for developing smart catalysts that exhibit both excellent activity and air stability. We synthesized a novel nickel phosphide nanoalloy (nano-Ni2P) with coordinatively unsaturated Ni active sites. Unlike conventional air-unstable non-noble metal catalysts, nano-Ni2P retained its metallic nature in air, and exhibited a high activity for the hydrogenation of various substrates with polar functional groups, such as aldehydes, ketones, nitriles, and nitroarenes to the desired products in excellent yields in water. Furthermore, the used nano-Ni2P catalyst was easy to handle in air and could be reused without pretreatment, providing a simple and clean catalyst system for general hydrogenation reactions.

A Schiff-base receptor based on phenolphthalein derivate appended 2-furoic hydrazide: Highly sensitive fluorogenic turn on chemosensor for Al3+

Herein, a novel phenolphthalein-derived Schiff base fluorescence probe FF2H has readily been synthesized and applied to be fluorescence ”turn-on. probe for Al3+ sensing in aceto-nitrile (ACN) : HEPES (5.0 mu M, 50/50, v/v, pH = 7). The emission response of the chemo-sensor FF2H toward Al3+ depends on the metal chelation-enhanced fluorescence (CHEF) effect and CHEF prevents C = N isomerisation, the excited state intra-molecular (ESIPT), and PET process of the chemosensor FF2H. FF2H-Al3+ complexation (1:2 stoichiometry) was revealed by Job’s method and H-1-NMR titration. The detection limit (LOD) (3s/K) value of FF2H for Al3+ was estimated to be 7.0 nM, demonstrating that the chemosensor FF2H could be employed as a fluorogenic ”turn-on chemosensor to effectively and selectively to recognize Al3+.

Nitric Oxide Modulating Calcium Store for Ca2+-Initiated Cancer Therapy

Ions are essential to body, but sometimes can evolve into weapons to attack and destroy cells without systematic toxicity and drug resistance. Inspired by nitric oxygen as neurotransmitter in mediating Ca2+ release, NO nanodonors with high photoreactivity and stability are constructed with upconversion nanoparticles (UCNPs) coated by zeolitic nitro-/nitrile-imidazole framework-82 (ZIF-82), capable of near-infrared light (NIR) triggered NO generation and berbamine (BER) release, to achieve cancer therapy with the stored Ca2+ in cells. The spatial confinement effect of 2-nitroimidazole in ZIF-82 enables NO-releasing with tunable release kinetics. NO turns on the ryanodine receptors overexpressed in cancer cells for abrupt Ca2+ elevation; meanwhile, berbamine (BER) turns Ca2+-excretion pumps off to inhibit calcium efflux, resulting in intracellular Ca2+ overload induced apoptosis. This work provides the first example of regulating endogenous ions for cell killing, which holds promise as an effective cancer therapeutics that is complementary to traditional chemotherapeutics.

Ester Hydrogenation with Bifunctional Metal-NHC Catalysts: Recent Advances

Hydrogenation of ester to alcohol is an essential reaction in organic chemistry due to its importance in the production of a wide range of bulk and fine chemicals. There are a number of homogeneous and heterogeneous catalyst systems reported in the literature for this useful reaction. Mostly, phosphine-based bifunctional catalysts, owing to their ability to show metal-ligand cooperation during catalytic reactions, are extensively used in these reactions. However, phosphine-based catalysts are difficult to synthesize and are also highly air- and moisture-sensitive, restricting broad applications. In contrast, N-heterocyclic carbenes (NHCs) can be easily synthesized, and their steric and electronic attributes can be fine-tuned easily. In recent times, many phosphine ligands have been replaced by potent sigma-donor NHCs, and the resulting bifunctional metal-ligand systems are proven to be very efficient in several important catalytic reactions. This mini-review focuses the recent advances mainly on bifunctional metal -NHC complexes utilized as (pre)catalysts in ester hydrogenation reactions.

The Hallmarks of Copper Single Atom Catalysts in Direct Alcohol Fuel Cells and Electrochemical CO2 Fixation

Single-atom catalysts (SACs) are highly enviable to exploit the utmost utilization of metallic catalysts; their efficiency by utilizing nearly all atoms to often exhibit high catalytic performances. To architect the isolated single atom on an ideal solid support with strong coordination has remained a crucial trial. Herein, graphene functionalized with nitrile groups (cyanographene) as an ideal support to immobilize isolated copper atoms G(CN)-Cu with strong coordination is reported. The precisely designed mixed-valence single atom copper (G(CN)-Cu) catalysts deliver exceptional conversions for electrochemical methanol oxidation (MOR) and CO2 reduction (CO2RR) targeting a closed carbon cycle. An onset of MOR and CO2RR are obtained to be approximate to 0.4 V and approximate to-0.7 versus Ag/AgCl, respectively, with single active sites located in an unsaturated coordination environment, it being the most active Cu sites for both studied reactions. Moreover, G(CN)-Cu exhibited significantly lower resistivity and higher current density toward MOR and CO2RR than observed for reference catalysts.
