The first total synthesis of enantiopure methyl (3aR,4S5S,6R,6aS)-4-benzyloxycarbonylamino-6-hydroxy-2,2-dimethyl-tetrahydro-3aH-cyclopenta[d][1,3]dioxole-5-carboxylate has been carried out according to our recent novel strategy for the transformation of nitrohexofuranoses into cyclopentylamines. This approach is based on an intramolecular cyclization that leads to 2-oxabicyclo[2.2.1]heptane derivatives. E1cb elimination of the methoxy substituent was observed when attempting to incorporate these beta-amino acid into peptides. As a result, the synthesis and incorporation of the first polyhydroxylated 5-aminocyclopent-1-enecarboxylic acid into peptides were developed. (C) 2010 Published by Elsevier Ltd.

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.

New Advances in Chemical Research, April 2021. Reactions catalyzed within inorganic and organic materials and at electrochemical interfaces commonly occur at high coverage and in condensed media. 43157-50-2, Name is 2-Thioadenosine, SMILES is S=C1NC2=C(N=CN2[C@@H]3O[C@H](CO)[C@@H](O)[C@H]3O)C(N)=N1, belongs to dioxole compound. In a document, author is Matos, M. Agostinha R., introduce the new discover, Recommanded Product: 2-Thioadenosine.

The standard (p degrees = 0.1 MPa) molar energies of combustion in oxygen, at T = 298.15 K, of four 1,3-benzodioxole derivatives (5-oxoethyl-1,3-benzodioxole, 5-cyano-1,3-benzodioxole, 5-nitro-1,3-benzodioxole, and 5-methyl-1,3-benzodioxole) were measured by static bomb calorimetry. The standard molar enthalpies of vaporization or of sublimation, at T = 298.15 K, were measured by Calvet microcalorimetry. Combining these results, the standard molar enthalpies of formation of the compounds in the gas phase, at T = 298.15 K, have been calculated: 5-oxoethyl-1,3-benzodioxole (-319.3 +/- 2.8) kJ.mol(-1); 5-cyano-1,3-benzodioxole (-23.2 +/- 2.2) kJ.mol(-1); 5-nitro-1,3-benzodioxole (-176.0 +/- 3.2) kJ.mol(-1) and 5-methyl-1,3-benzodioxole (-184.7 +/- 3.5) kJ.mol(-1). The most stable geometries of all the compounds were obtained using the density functional theory with the B3LYP functional and two basis sets: 6-31G** and 6-311G**. The nonplanarity of the molecules was analyzed in terms of the anomeric effect, which is believed to arise from the interaction between a nonbonded oxygen p(pi) orbital and the empty orbital sigma*(CO) involving the other oxygen atom. Calculations were performed to obtain estimates of the enthalpies of formation of all the substituted benzodioxoles using appropriate isodesmic reactions. There is good agreement between theoretical and experimental results. This agreement allows us to estimate the enthalpies of formation of some 1,3-benzodioxole derivatives whose experimental study was impossible.

Nanocomposite membranes based on nano-sized SiO2 particles with chemical coupling to the polymer matrix are described with special emphasis on gas permeation properties. In this paper, poly(ether imide) with reactive imide rings in the backbone was used as the matrix to which the SiO2 particles were chemically bonded via an amine-containing silane coupling agent. Four types of nanocomposite membranes were prepared by solution casting and melt processing and characterized in terms of morphology and void volume formed due to adding SiO2 particles. The relative gas permeability of the nanocomposite with chemical coupling to matrix was decreased by the presence of SiO2 particles. Diffusion coefficients computed from time lag data also decreased with SiO2 content. However, solubility coefficients computed by dividing the experimental permeability by the diffusivity obtained from the observed time lag increased with SiO2 content contrary to simple composite theory. These permeation properties are discussed in terms of the void volume fraction estimated by density observations. In addition, TEM and SEM were used to explore the morphology of these nanocomposite membranes. (c) 2006 Elsevier Ltd. All rights reserved.

A 4-Chloro-5-trifluoromethyl-2,2,4-trifluoro-1,3-dioxolane (1) was synthesised by reaction of CF2(OF)(2) with CF3-CH=CFCl; the elimination of HCl from (1) in basic conditions led to the formation of dioxole perfluoro-4-methyl-1,3-dioxole (2). Both these synthetic steps gave the corresponding product in high yield.

Formation of the carbonyl oxides 3, via the furan endo-peroxides 1, can be accomplished only by dye-sensitized photo-oxygenation of 2-alkoxyfurans 2 unsubstituted at C-4, electron-withdrawing substituents at C-3 making the formation selective. Hydrogen or phenyl substituents at C-3 give rise either to carbonyl oxides 3 or to 3H-1,2-dioxoles 8, the predominance of one over the other being dependent on the polarity of the solvent. For the first time, direct evidence for the formation of a 3H-1,2-dioxole, 8e, has been obtained.

Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. 4330-21-6, Name is Hoffer’s chlorosugar, SMILES is O=C(O[C@@H]1[C@@H](COC(C2=CC=C(C)C=C2)=O)O[C@H](Cl)C1)C3=CC=C(C)C=C3, belongs to dioxole compound. In a document, author is Skrobiszewski, Andrzej, introduce the new discover, Application In Synthesis of Hoffer’s chlorosugar.

Eighteen racemic beta-aryl-gamma-lactones derived from simple aromatic aldehydes have been obtained in the chemical synthesis. Iodolactones (5c and 6c) were synthesized from (E)-4-(benzo[d][1′,3′]-dioxol-5′-yl)-but-3-en-2-one (1). Reductive dehalogenation of iodolactones 5a-c and 6a-c afforded gamma-ethyl-gamma-lactones (7a-c, 8a-c) whereas the unsaturated lactones (9a-c, 10a-c) were obtained by dehydrohalogenation of iodolactones. All synthesized lactones were fully characterized by spectroscopic data (NMR, IR, HRMS) and subjected to the tests on the antifeedant activity towards Tribolium confusum, Trogoderma granarium and Sitophilus granaries as well to the tests on the antifungal activity towards four Fusarium species. The biological tests allowed to find some relationships between the structure and biological activity of the compounds studied. gamma-Ethyl- gamma-lactones 7a-c, 8a-c and unsaturated lactones 9a-c, 10a-c were usually stronger antifeedants than their parent iodolactones 5a-c and 6a-c. trans-Iodolactones 6a-c were more active than cis isomers 5a-c both in antifeedant and antifungal assays. The structure of aromatic substituent was the key factor in antifungal activity. The lactones with benzo [d][1,3]dioxole ring (5c, 6c, 7c, 8c, 9c) were the most active whereas those with unsubstituted benzene ring exhibited almost no activity.
