Mohlmann, Lennart published the artcileOrganocatalytic Enantioselective Synthesis of Tetrahydrofluoren-9-ones via Vinylogous Michael Addition/Henry Reaction Cascade of 1,3-Indandione-Derived Pronucleophiles, Safety of (E)-4-(2-Nitrovinyl)benzonitrile, the publication is Organic Letters (2016), 18(4), 688-691, database is CAplus and MEDLINE.

An unprecedented organocatalytic enantioselective vinylogous Michael addition and Henry cyclization cascade is presented for the synthesis of highly substituted tetrahydrofluoren-9-ones employing novel 1,3-indandione-derived pronucleophiles and nitroalkenes. Following a very simple protocol, a wide range of products were obtained in good to excellent yields and with excellent enantioinduction (43-98% yields, up to 98% ee). The reaction proceeded with excellent diastereocontrol despite the simultaneous generation of four stereogenic centers. Surprisingly, when 2-(1-phenylethylidene)-1H-indandione was used as a pronucleophile, no cyclization was observed, and only Michael addition adducts were furnished in very good yields and excellent enantioselectivities.

A three-component reaction has been developed for the construction of multiaryl-substituted pyrrole derivatives from arylketones, amines, and nitrovinylarenes under metal-free conditions. Hence, homologous 1,2,4-triaryl-substituted pyrrole products were obtained in good to high yields. Furthermore, 2,3,5-triaryl-substituted pyrroles were selectively formed in the absence of nitrovinylarenes. The photophys. properties of some pyrrole products have been investigated to show good aggregation-induced emission (AIE) activity.

Johansson, Maria H. published the artcileThe influence of metal coordination on ligand geometry: the structure of 2-(diphenylphosphino)acetophenone and bis(2-(diphenylphosphino)acetophenone)palladium(II) bistriflate, Safety of Tetrakis(acetonitrile)palladium(II) Ditriflate, the publication is Journal of Molecular Structure (2002), 606(1-3), 51-59, database is CAplus.

The structures of 2(diphenylphosphino)acetophenone and bis(2(di-Ph phosphino)acetophenone)palladium(II) bistriflate were determined by x-ray crystallog. The ligand is of interest because its P,O donor set combines the hard and soft properties. In the Pd-complex, which was prepared by treating tetrakisacetonitrile-Pd-bistriflate with 2-(diphenylphosphino)acetophenone in CH₂Cl₂ for 4 h at room temperature, the O-coordination provides a masked coordinative unsaturation The ligand crystallizes in the monoclinic space group P2₁/c with a 11.050(2), b 16.052(3), c 9.7082(19) Å, β 109.58(3)°, Z = 4. The Pd-complex crystallizes in the orthorhombic space group P2₁2₁2₁ with a 11.867(2), b 18.162(4), c 19.603(4) Å, Z = 4. Both structures were solved by direct methods and the refinements resulted in the R-values of 0.059 and 0.043, for the organic compound and the Pd compound, resp. Two bi-dentate ligand binds to Pd(II) in a cis-configuration. At. coordinates are given. The Pd-O distances are 2.060(3) and 2.096(2) A and the Pd-P distances 2.2290(10) and 2.2294(10) A, showing a large trans-influence of the P atoms. Half-normal probability plot analyses indicate that the s.u.’s are largely underestimated in the studied structures. The bond-angles around the P atom and the orientation of the keto-substituted Ph rings as well as the orientation of the keto-groups are highly affected by metal complexation.

Menzies, Donna J. published the artcileAdhesive Prebiotic Chemistry Inspired Coatings for Bone Contacting Applications, Name: 2-Aminomalononitrile 4-methylbenzenesulfonate, the publication is ACS Biomaterials Science & Engineering (2017), 3(5), 793-806, database is CAplus and MEDLINE.

New and improved bone-contacting medical devices are required to provide excellent bioactivity at the biointerface. Here, we have used coatings based on prebiotic chem. inspired polymerization of aminomalonitrile (AMN) in combination with comonomers 3,4-di- and 3,4,5-trihydroxybenzaldehyde (DHBA and THBA). The comonomers were incorporated into the AMN coatings to enhance polymerization kinetics, adhesive properties, metal binding efficacy, and human mesenchymal stem cell (hMSC) response. Incorporation of DHBA and THBA as sep. comonomers enhanced the polymerization kinetics compared to that of AMN polymerization alone, with 30 mol % THBA (30T) resulting in a 6-fold increase in thickness over 24 h. Furthermore, the adhesion of AMN coatings to silicon was enhanced when copolymerized with the HBA monomers, where the interfacial adhesion of the 30T coating was increased 20-fold. The ability of the coatings to incorporate zinc ions was investigated, and XPS anal. demonstrated that incorporating 30T increased the binding efficiency 4-fold compared to that of AMN alone. The attachment, proliferation, and morphol. of human mesenchymal stem cells (hMSC) on these coatings was investigated and reported. Finally, the utility of the coatings as osteogenic support matrixes via the induced osteogenic differentiation of hMSCs is reported. The AMN and 30T coatings resulted in the greatest efficiency of osteogenic differentiation, as measured by intracellular ALP activity and mineralization. Incorporation of zinc had a stimulatory effect on hMSC proliferation with 30T coatings, while enhanced mineralization was observed with the zinc functionalized AMN and 30T coatings. This study highlights the potential of prebiotic chem. inspired coatings in biomedical applications.

Cheng, Qiuli published the artcileAntifouling and Antibacterial Polymer-Coated Surfaces Based on the Combined Effect of Zwitterions and the Natural Borneol, Recommanded Product: 2-Aminomalononitrile 4-methylbenzenesulfonate, the publication is ACS Applied Materials & Interfaces (2021), 13(7), 9006-9014, database is CAplus and MEDLINE.

The development and application of natural antibacterial materials have always been the focus of biomedical research. Borneol as a natural antibacterial compound has received extensive attention. However, the hydrophobicity caused by its unique structure limits its application range to a certain extent. In this study, we combine zwitterionic 2-methacryloyloxyethyl phosphorylcholine (MPC) with a complex bicyclic monoterpene structure borneol compound and prepare an excellent antifouling and antibacterial surface via the Schiff-base bond. The prepared coating has excellent hydrophilicity verified by the contact angle (CA), and its polymer layer is confirmed by XPS. The zwitterion MPC and borneol moieties in the copolymer play a coordinating role, relying on super hydration and the special stereochem. structure to prevent protein adsorption and inhibit bacterial adhesion, resp., which are demonstrated by bovine serum albumin (BSA) adsorption and antibacterial activity test. Moreover, the water-soluble borneol derivative as the antibacterial surfaces we designed here was biocompatible toward MRC-5 (lung fibroblasts), as showed by in vitro cytotoxicity assays. Such results indicate the potential application of the as-prepared hydrophilic surfaces in the biomedical materials.
