Crack-free and smooth surfaces of poly[4,5-difluoro 2,2-bis-(trifluoroinethyl)-1,3 dioxole]-co-tetrafluoroethylene (TFE-co-TFD) films have been deposited by sol-gel technique on polished AISI 440C steel and quartz substrates. The deposited films have been subjected to annealing at different temperatures ranging from 100 to 500 degreesC for 1 h in argon atmosphere. The as-deposited and annealed films (below 300 degreesC) on quartz have shown antireflection behaviour in the UV region. Surface properties of the films have been examined by employing scanning electron microscopy, energy dispersive X-ray analyser, for morphology and elemental composition. Adhesion strength failure was measured by scratch resistance test technique indicated good adhesion of the films on the substrate. It was found that as the annealing temperature increased from 100 to 400 degreesC, nanostructured sphere like balls were formed which in turn has shown increase in the contact angle for water from 122degrees to 247degrees. No change in the water contact angle (122degrees) has been observed when the films deposited at room temperature were heated in air from 30 to 80 degreesC indicating thermal stability of the coating.

The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic, and theoretical assessments of solvent structures and their interactions with reaction intermediates and transition states. 98760-08-8, Name is (2R,3S)-1,2-Epoxy-3-(Boc-amino)-4-phenylbutane, SMILES is O=C(N[C@@H](CC1=CC=CC=C1)[C@@H]2CO2)OC(C)(C)C, in an article , author is Dau, Phuong V., once mentioned of 98760-08-8, SDS of cas: 98760-08-8.

The synthesis and physical properties of dioxole functionalized metal-organic frameworks (MOFs) are reported. Combination of benzo[d][1,3] dioxole-4,7-dicarboxylic acid (dioxole-BDC) and Zn(II) under solvo-thermal conditions yields either an isoreticular metal-organic framework analog (IRMOF-1-dioxole) or a new MOF material (MOF-1-dioxole). With the addition of a co-ligand, namely 4,4′-bipyridine, a mixed-linker Zn(II)-paddlewheel MOF (BMOF-2-dioxole) is obtained. The structure of all three MOFs has been determined by single-crystal X-ray diffraction studies. MOF-1-dioxole reveals that the dioxole group binds to the Zn(II) ions, while there is no such binding in IRMOF-1-dioxole or BMOF-2-dioxole, hence preserving the parent topology of these frameworks. Thermal gravimetric analysis and gas sorption studies reveal quite different physical properties for each of these functionalized MOFs.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 98760-08-8 is helpful to your research. SDS of cas: 98760-08-8.

A divergent synthesis of 10 icetexane natural products based on a proposed biogenetic cationic ring expansion of a reduced carnosic acid derivative is described. Of these icetexanes, (+)-salvicanol, (-)-cyclocoulterone, (-)-coulterone, (-)-obtusinone D, and (-)-obtusinone E have been synthesized for the first time. In addition, the hypothesis for the non-enzymatic biogenesis of benzo[1,3]dioxole natural products has been experimentally investigated. Additional experimental evidence for the abiotic formation of the methylenedioxy unit is provided, as photolysis of the quinone (+)-komaroviquinone resulted in the formation of the [1,3]dioxole-containing natural product (-)-cyclocoulterone and (+)-komarovispirone.

Proline is a proteinogenic amino acid in which the side chain forms a ring, the pyrrolidine ring. This is a five-membered ring made up of four carbons and one nitrogen. Here, we study the evolutionary significance of this ring size. It is shown that the size of the pyrrolidine ring has the advantage of being nearly planar and strain-free, based on a general mathematical assertion saying that the angular sum of a polygon is maximum if it is planar and convex. We also provide a sketch of the proof to this assertion. The optimality of the ring size of proline can be derived from a triangle inequality for angles. Quasi-planarity is physiologically significant because it allows an easier and evolutionarily old type of fit into binding grooves of proteins with which proline-rich proteins interact. Finally, we present a comparison with other planar, nearly planar and non-planar biomolecules such as neurotransmitters, hormones and toxins, involving, for example, aromatic rings, cyclopentanone and 1,3-dioxole.

BACKGROUND: Numerous works have been published on the chemical modification of chitosan; this polymer is still being modified, leading to various derivatives with improved properties. In the present study, heterocyclic aldehydes including furan-2-carbaldehyde, 5-methylfuran-2-carbaldehyde, 3-pyridine carboxyaldehyde, benzo[d][1,3]dioxole-5-carbaldehyde and 4-oxo-4H-chromene-3-carbaldehyde were reacted with chitosan by a reductive alkylation reaction to produce for the first time five new N-heterocyclic chitosan derivatives to improve the biological activity of chitosan against the most important economic plant pests including fungi and insects, in particular the cotton leafworm Spodoptera littoralis. RESULTS: The chemical structures of the synthesized compounds were confirmed by H-1 NMR spectroscopy and the degree of substitution ranged from 0.30 to 0.43. The fungicidal assessment was investigated in vitro using a mycelia radial growth inhibition technique against soil-borne pathogenic fungi Fusarium oxysporum and Pythium debaryanum and the rice leaf blast Pyricularia grisea. The results showed that N-[(5-methylfuran-2-yl)methyl] chitosan was the most active against P. grisea with an EC50 value of 0.919mg mL(-1) while N-(benzo[d][1,3]dioxol5-ylmethyl) chitosan and N-(methyl-4H-chromen-4-one) chitosan exhibited the most potent fungicidal activity against P. debaryanum and F. oxysporum. An insecticidal bioassay against the larvae of S. littoralis showed that N-(methyl-4H-chromen-4-one) chitosan exhibited a significant growth inhibition and antifeedant activity among the synthesized compounds. CONCLUSION: The chemical modification of chitosan molecule with a heterocyclic moiety led to an enhancement in the biological activity against the plant pathogenic fungi F. oxysporum, P. debaryanum and P. grisea and the cotton leafworm insect S. littoralis.

THE CHEMOENZYMATIC reaction of selected aldehydes, namely 2-chlorobenzaldehyde (1a), 4-fluorobenzaldehyde (1b), benzo[d][1,3] dioxole-5-carbaldehyde (1c) and/or 2,3-dihydrobenzo [b] [1,4]dioxine-6-carbaldehyde (1d) with hydrogen cyanide in presence of (R)-oxynitrilase (R)-Pa HNL [EC 4.1.2.10] from almonds, as a chiral catalyst, gave the optically active cyanohydrin enantiomers (R)2a-c, respectively. Acetone cyanohydrin (3), was also used, as a transcyanating agent, to give the same products. The racemic cyanohydrins (R, S)-2a-d have been synthesized, as well, by treating compounds 1a-d with aqueous potassium cyanide solution in presence of a saturated solution of sodium metabisulphite (Na2S2O5). The optical purity of cyanohydrins (R)-2a-c was determined through their derivatization with (S)-naproxen chloride (S)-5 to the respective diastereomers (R, 2S)-6a-c which were obtained in diastereomeric excess (de) values up to 93 % (H-1 NMR). Heating compounds (R)-2a, b and / or their racemic analogues (R, S)-2a-c with concentrated hydrochloric acid gave the respective alpha-hydroxycarboxylic acids 7a-c. Moreover, reduction of cyanohydrins (R, S)-2b,c under different conditions resulted in a hydrodecyanation giving the respective primary alcohols 8a, b. Structures and configurations of the new compounds were confirmed with compatible elementary microanalyses and spectroscopic (IR, H-1 NMR, C-13 NMR, MS and single crystal X-ray crystallography) measurements. The antimicrobial activity of derivatives 6a-d against four bacterial species (Bacillus subtilis, Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa) and two fungi (Aspergillus flavus and Candida albicans) were undertaken. Moreover, compounds (R,2S)-6b, (R, 2S)(S, 2S)-6b and (R, 2S)-6c were screened for their in virto antitumor activity against three human solid cancer cell lines (HCT 116, HepG2 and MCF-7). In general, the tested compounds were found inactive or showed weak activities in comparison with the standard drugs.

In spite of early reports by Birch, we demonstrated that treatment of benzodioxoles with sodium in ammonia in the presence of methanol almost quantitatively yields the corresponding dihydro compounds. Despite their poor stability these compounds are synthetically useful. Treatment of 5-isobutyl-4,7-dihydrobenzo[1,3]dioxole with bromotrimethylsilane gives 6-hydroxy-3-isobutylcyclohex-2-enone in 80% yield. Treatment of 4,7-dihydrobenzo[1,3]dioxole with potassium in liquid ammonia in the presence of iron(III) chloride leads to 3a,4-dihydrobenzo[1,3]dioxole in high yield..
