In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 50446-44-1, name is 5′-(4-Carboxyphenyl)-[1,1′:3′,1”-terphenyl]-4,4”-dicarboxylic acid, introducing its new discovery. name: 5′-(4-Carboxyphenyl)-[1,1′:3′,1”-terphenyl]-4,4”-dicarboxylic acid

Growth of covalently bonded Sierpi?ski triangles (CB-STs) on metal surfaces was investigated by scanning tunneling microscopy (STM). Three synthetic strategies (namely, dehydration condensation, cyclotrimerization coupling and Schiff-base reactions) were used to fabricate CB-STs. Second-generation CB-STs were obtained at the solid-vacuum interface utilizing the Schiff-base reaction between 4,4??-dialdehyde-1,1?:3?,1??-terphenyl (TPDAL) and 1,3,5-tris(4-aminophenyl)benzene (TAPB) on Au(111). The CB-ST patterns persist at annealing temperatures as high as 500 K. Homotactic three-fold motifs, insufficient migration and irreversible covalent reaction are the main limitations for growing higher-generation STs. The present results provide new insights on the growth of STs on metal surfaces.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

The spacer structure of homobivalent quinazolinimes acting as potent acetyl-(AChE)- and butyrylcholinesterase (BChE) inhibitors was chemically modified introducing tertiary amine and acyl-amide moieties, and the activities at both ChEs were evaluated. Molecular docking was applied to explain the data and probe the capacity of the mid-gorge site of both ChEs. The novel spacer structures considerably alter the biological profile of bivalent quinazolinimines with regard to both inhibitory activity and selectivity. Mutual interaction of binding to the various sites of the enzymes was further investigated by applying also different spacer lengths and ring sizes of the alicycle of the tricyclic quinazolinimines. In order to achieve selectivity toward BChE and to improve inhibitory activities, the spacer structure was optimized and identified a highly potent and selective BChE inhibitor.

The first synthesis of the cyclic peptide natural product, argadin is reported. Use of a solid-phase approach featuring side-chain resin attachment through histidine and a novel protecting group strategy allows rapid and efficient access to the argadin backbone, whereupon the unusual 3-amino-5-hydroxy-2-pyrrolidone moiety of the peptide is introduced by oxidative cyclisation of a homoserine residue. Argadin is shown to exist as a 5:1 mixture of diastereoisomers at the 5-hydroxy centre of the pyrrolidone ring, and inhibits a representative family-18 chitinase (ChiB1 from Aspergillus fumigatus) with Ki = 33 nM. The high-resolution X-ray crystal structure of synthetic argadin in complex with the same enzyme shows the binding of a single diastereoisomer as previously observed with the authentic natural product.

In a article，once mentioned of 581-50-0

Ruthenium complexes with bipyridine-analogous quaternized (N,C) bidentate ligands [RuL(bpy)2](PF6)2 (bpy = 2,2?-bipyridine, (1), L = L1 = N?-methyl-2,4?- bipyridinium; (2), L = L2 = N?-methyl-2,3?-bipyridinium) were synthesized and characterized. The structure of complex 2 was determined by the X-ray structure analysis. The 13C{1H} NMR spectroscopic and cyclic voltammetric studies indicate that the coordination modes of these ligands are quite different, that is, the C-coordinated rings of (N,C)-ligands in 1 and 2 are linked to ruthenium(II) with a pyridinium manner and a pyridinylidene one, respectively. The ligand-localized redox potentials of 1 and 2 also revealed the substantial difference in the electron donating ability of both ligands.

A new one-pot method of reductive amination is used to prepare a chiral C2 symmetrical amine. This amine is used for the synthesis of a new chiral phosphoramidite ligand. The new ligand is, in turn, used to illustrate the enantioselective copper-catalyzed allylic substitution with Grignard reagents. When a remote double bond is located on the Grignard reagent, the newly formed alkene undergoes an in situ ruthenium-catalyzed ring-closing metathesis to afford the cyclized product in 77% yield and 94% ee.
