Crystal engineering construction of caffeic acid derivatives with potential applications in pharmaceuticals and degradable polymeric materials

Natural products are precious feedstock in drug discovery and sustainable materials. This work using crystal engineering strategy, visible light, and solvent-free cycloaddition successfully constructed two caffeic acid derivatives, rel-(1R,2R,3S,4S)-2,4-bis(3,4-dihydroxyphenyl)cyclobutane-1,3-dicarboxylate and rel-(1R,2R,3S,4S)-2,4-bis(3,4-dihydroxyphenyl)cyclobutane-1,3-dicarboxylic acid. Because of the multiple stereocenters, it is challenging to prepare those compounds using traditional organic synthesis methods. The crystal engineering Hirshfeld surface analysis and 2D intermolecular interaction fingerprints were applied to synthetic route design. The light resources used in this work was visible LED or free, clean, and renewable sunlight. The evidence suggested that pure stereoisomer was obtained demonstrating the stereospecificity and efficiency of the topochemical cycloaddition reaction. The derivatives exhibited free radical scavenging and antioxidant biological activities, as well as the potential inhibitory activity of fatty acid binding proteins. One of the derivatives is the precursor of the natural product shimobashiric acid C which paves the way for the total synthesis and further study of shimobashiric acid C. In addition, the derivatives possess photodegradability at a specific wavelength, which is very attractive for green degradable polymeric materials.

FMPhos: Expanding the Catalytic Capacity of Small-Bite-Angle Bisphosphine Ligands in Regioselective Alkene Hydrofunctionalizations

In contrast to the plethora of large-bite-angle bisphosphine ligands available to transition-metal catalysis, the development of small-bite-angle bisphosphine ligands has suffered from the limited structural variations accessible on their single-atom-containing backbones. Herein, we report the design and applications of a discrete very small bite-angle bisphosphine ligand, namely, FMPhos. Featuring a fluorene-methylene unit appended on the single-carbon linker, the ligand harbors an unusually rigid backbone that presumably stabilizes its complexation with transition metals during catalysis. Compared with the known dppm ligand, it exhibited superior reactivity and regioselectivity in a number of alkene hydrofunctionalization reactions, catalyzed by iridium and rhodium.

Adsorption behavior and application performance of branched aliphatic alcohol polyoxyethylene ether phosphate

Phosphate ester surfactants has been extensively studied in the recent past. However, the information on detailed studies on branched alcohol ether phosphates is only sparsely reported in the literature. To help cover this gap in the research of branched alcohol ether phosphates, in this article, branched alcohol ether phosphates (A(13)E(5)P, A(10)E(5)P) as the main research object and linear alcohol ether phosphates (A(12)E(5)P) as the control group. By measuring the static surface tension (SST), dynamic surface tension (DST) and dynamic contact angle (DCA) of the samples, the adsorption performance of AEP with different hydrophobic structures was studied. Studies have shown that the branching structure strengthens the hydrophobic effect, which brought lower surface tension, higher surface activity, and more excellent wetting properties. And it is found that the change of ionic strength has a greater effect on the branched AEP. In addition, the branched AEP showed better permeability, while linear AEP showed better foam performance, antistatic performance and softness. This paper shows that the branched structure of AEP is beneficial to improve the adsorption performance of the gas-liquid interface, but not to the adsorption of the solid-liquid interface.

Preparation of a boronate-affinity monolithic column for adsorption of nucleosides

Chitosan is a considerably versatile and promising biomaterial and can easily form a 3D hierarchical porous scaffold. In this work, a novel boronate-affinity monolithic column modified with a boronic acid-chitosan complex was prepared and characterized by different methods such as Fourier transform infrared spectroscopy, scanning electron microscopy, thermal gravimetric analysis, specific surface area analysis and pore size distribution analysis. The synthesized monolithic column was used for polymer monolithic microextraction combined with high performance liquid chromatography for the simultaneous determination of cytidine, uridine, inosine, and guanosine in milk powder samples. Several parameters affecting extraction efficiency, including the eluent proportion, eluent flow rate, sample flow rate, sample volume, and sample pH were investigated. The boronate-affinity monolithic column showed high enrichment ability due to the selective formation of cyclic borate esters between nucleosides and boronic acid groups at high pH and the release of cyclic borates at low pH values. Under the optimum operating conditions, the linear range was 0.1-50 mu g mL(-1), and the correlation coefficients were in the range of 0.9993-0.9994. The LOD and LOQ were in the range of 0.0027-0.0034 and 0.0090-0.011 mu g mL(-1), respectively. In addition, the results of recovery and relative standard deviation were satisfactory.

Ruthenium-Catalyzed Selective Hydroboronolysis of Ethers

A ruthenium-catalyzed reaction of HBpin with substituted organic ethers leads to the activation of C-O bonds, resulting in the formation of alkanes and boronate esters via hydroboronolysis. A ruthenium precatalyst, [Ru (p-cymene)Cl](2)Cl-2 (1), is employed, and the reactions proceed under neat conditions at 135 degrees C and atmospheric pressure (ca. 1.5 bar at 135 degrees C). Unsymmetrical dibenzyl ethers undergo selective hydroboronolysis on relatively electron-poor C-O bonds. In arylbenzyl or alkylbenzyl ethers, C-O bond cleavage occurs selectively on C-Bn-OR bonds (Bn = benzyl); in alkylmethyl ethers, selective deconstruction of C-Me-OR bonds leads to the formation of alkylboronate esters and methane. Cyclic ethers are also amenable to catalytic hydroboronolysis. Mechanistic studies indicated the immediate in situ formation of a mono-hydridobridged dinuclear ruthenium complex [{(eta(6)-p-cymene)RuCl}(2)(mu-H-mu-Cl)] (2), which is highly active for hydroboronolysis of ethers. Over time, the dinuclear species decompose to produce ruthenium nanoparticles that are also active for this transformation. Using this catalytic system, hydroboronolysis could be applied effectively to a very large scope of ethers, demonstrating its great potential to cleave C-O bonds in ethers as an alternative to traditional hydrogenolysis.

Mesomorphism of novel stilbene-based bent-core liquid crystals

A series of asymmetric bent-core liquid crystals, bearing the stilbene moiety in the side wing, was synthesised and characterised. Structural modifications of the non-stilbene wing resulted in formation of various mesophases. Compounds 1 and 3 with an ester linking group between the phenyl rings in this wing have an enantiotropic non-polar smectic-type mesophase, while compound 2, incorporating the biphenyl moiety, has a ferroelectric SmCaPF phase. The molecules of 2 undergo photoisomerisation in solution under UV irradiation, while the mesophases are unstable and UV irradiation leads to irreversible changes. The mesophases of 1 and 3 do not show any electro-optical switching and polarisation current. Applying low frequency AC voltage on a planarly aligned film of compound 2, smectic domains grow, while the birefringence and an image flickering increase. The observed features of these compounds identify stilbene as an attractive moiety in the design of advanced materials based on bent-core molecules.

Iron-catalysed enantioconvergent Suzuki-Miyaura cross-coupling to afford enantioenriched 1,1-diarylalkanes

The first stereoconvergent Suzuki-Miyaura cross-coupling reaction was developed to afford enantioenriched 1,1-diarylalkanes. An iron-based complex containing a chiral cyanobis(oxazoline) ligand framework was best to obtain enantioenriched 1,1-diarylalkanes from cross-coupling reactions between unactivated aryl boronic esters and benzylic chlorides. Enhanced yields were obtained when 1,3,5-trimethoxybenzene was used as an additive, which is hypothesized to extend the lifetime of the iron-based catalyst. Exceptional enantioselectivities were obtained with challenging ortho-substituted benzylic chlorides.
