Template synthesis and X-ray structure of the tris-glyoximate iron(II) clathrochelates with terminal reactive groups

One-pot template condensation of glyoxime with the corresponding functionalized phenylboronic acids on an iron(II) ion as a matrix afforded 3- and 4-substituted phenylboron-capped tris-glyoximate iron(II) clathrochelates with terminal amine, formyl (acetal) and vinyl groups; those with acetal groups were converted into the formyl-terminated cage complexes using H+-catalyzed hydrolysis. The complexes obtained were characterized using elemental analysis, MALDI-TOF mass spectrometry, IR, UV?Vis,1H and13C NMR spectroscopies, and by single crystal X-ray diffraction (for three of these clathrochelates). Their molecules possess a geometry intermediate between a trigonal prism (TP) and a trigonal antiprism (TAP) and the bite angles alpha remain almost constant being in the range 77?79, whereas the heights h of FeN6-coordination polyhedra depend on the distortion angle phi values (from 12.2 to 20.7) thus being in the range 2.36?2.37?A. An encapsulated iron(II) ion is situated almost in the centre of cage frameworks and the average chelate [Formula presented] bonds in these tris-glyoximate frameworks are substantially shorter than those for their aliphatic and aromatic analogs. The crystal packings are governed by weak supramolecular hydrophobic interactions and an absence of the steric hindrances between the ribbed substituents (hydrogen atoms) allowed to form intermolecular pi?pi interactions. As follows from single crystal X-ray diffraction data, the synthesized macrobicyclic tris-glyoximates with reactive terminal groups, which the macrobicyclic molecules contain no bulky ribbed substituents, have large ligand aspect ratio and, therefore, they seem to be promising syntones and building blocks for preparation of covalent (including imine and amine) and coordination metallomacrocycles, MOFs and cages (capsules) with big voids and cavities as hosts, suitable for inclusion of various organic and inorganic guests.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. category: pyridazine, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 14161-11-6, in my other articles.

N-aryl heterocycles via coupling reactions with arylboronic acids

Compounds having a partial 2-pyridone structure or 3-pyridazinones can be selectively N-arylated with phenylboronic acids according to the procedure described by Chan and Lam. This procedure leads to N5-arylated imidazo[4,5- c]pyridin-4-ones, precursors of potent factor Xa inhibitors. In addition, the synthesis of N-aryl substituted pyrrole- and indole-2-carboxylic acid esters is described. In the indole series this procedure offers a flexible entry in the synthesis of different 1,3-diaryl-2-carboxyindoles.

Evaluation of potential genotoxic and cytotoxic effects of deltamethrin insecticide on somatic chromosomes of Helianthus annuus L.

In this research, the genotoxic and cytotoxic effects of the insecticide deltamethrin (DEL) on the root meristem cells of sunflowers (Helianthus annuus L.) were investigated. The lethal dose (LD50) value was determined as approximately 1?ppm in the sunflower root growth tests. The roots were treated with 1 (LD50), 0.25 (LD50/4), 0.5 (LD50/2) and 2?ppm (LD50 ¡Á2) concentrations of DEL for 24, 36 and 48?h, with a control for each combination. Occurring morphological changes such as reduction of root elongation and discoloration in sunflower roots were observed with the using DEL concentrations. The mitotic index and mitotic abnormalities were determined in both control and test groups. Mitotic index reduced with increasing the insecticide concentration at each exposure time. The mitotic abnormalities were recorded as disturbed prophase, c-mitosis, stickiness, laggards and chromatid bridges. In addition, micronucleus was observed at interphase and its frequency was calculated in the test solutions.

Synthesis of N-alkyl-N-methyl amino acids. Scope and limitations of base-induced N-alkylation of Cbz-amino acids

The reaction of N-benzyloxycarbonyl derivatives of aliphatic amino acids with NaH/alkyl iodides gave the corresponding N-Cbz-N-alkyl derivatives in good to high yields. The scope and limitations of this simple N-alkylation reaction were investigated as a convenient and flexible attempt to prepare unsymmetrically N,N-diprotected alpha-amino acids. The procedure is based on the N-alkylation of N-carbamoyl amino acids, a one-pot deprotection/protection sequence without extensive purification of the products. Protection of the carboxyl function is not required while the starting materials are inexpensive and commercially available.

Studies on anti-platelet agents. V. Synthesis and structure-activity relationship of 3-substituted 5,6-bis(4-methoxyphenyl)-1,2,4-triazines

The syntheses and structure-activity relationships of a series of 3-substituted 5,6-bis(4-methoxyphenyl)-1,2,4-triazines as anti-platelet agents based on cyclooxygenase (CO) inhibition are described. Of these compounds, 1-[5,6-bis(4-methoxyphenyl)-1,2,4-triazin-3-yl]carbonyl-4-methylpipera zine (10) exhibited potent CO inhibition in vitro (IC50 = 2.8 x 10-7 M) with vasodilatory activity (ED50 = 4.5 x 10-5 M). Compound 10 also showed potent ex vivo activities, completely preventing platelet aggregation induced by arachidonic acid and collagen at 6 h after oral administration of 3.2 and 1.0 mg/kg. The ex vivo potency of 10 is more than three times that of aspirin. Moreover, 10 demonstrated no gastrointestinal side effect in rats even at 100 mg/kg in spite of its potent CO inhibition activity, while aspirin, the most widely-used anti-platelet drug, showed gastrointestinal side effects in a dose-dependent manner (32, 100, and 320 mg/kg) in our study. These results suggested that 10 is a very attractive candidate for development as an anti-platelet drug since an aspirin-like anti-platelet agent, based on CO inhibition and being free from gastrointestinal side effects, is a major goal of thromboembolic research.
