Mucroniferanines A-G, lsoquinoline Alkaloids from Corydalis mucronifera

Five pairs of isoquinoline alkaloid enantiomers, mucroniferanines A-E (1-5), two inseparable epimeric pairs, mucroniferanines F and G (6, 7), and 10 known isoquinoline alkaloids (8-17) were obtained from Corydalis mucronifera. The structures were characterized using spectroscopic data analysis, and the absolute configurations were established by ECD and X-ray data analysis. The new compounds except for 3 possess a rare 9 methyl group in the isoquinoline alkaloids, and compounds 2 and 3 possess rare benzo[1,2-d:3,4-d]bis[1,3]dioxole moieties. It is the first report of stereoisomerism involving the 9-methyl phthalideisoquinoline alkaloids. Compounds (-)-4, 6, and 7 exhibited acetylcholinesterase inhibitory activities with IC50 values of 28.3, 12.2, and 11.3 mu M, respectively.

Spectroscopic studies and first-principles modelling of 2,2,4-trifluoro-5-trifluoromethoxy-1,3-dioxole (TTD) and TTD – TFE copolymers (Hyflono (R) AD)

Amorphous fluorinated optical polymers, characterized by high transparency in the visible and near infrared spectra, high glass transition temperature and very good resistance to chemical environment, have been developed by co-polymerisation of tetrafluoroethylene (TFE) and 2,2,4-trifluoro-5-trifluoromethoxy-1,3-dioxole (TTD). In this work we study at molecular level the effect of the introduction of the bulky TTD unit in a perfluoroalkyl chain. In particular the effect on the molecular structure and chain flexibility is investigated and spectroscopic markers correlated to chemical and structural defects are identified. The study includes a thorough experimental spectroscopic analysis (infrared and Raman spectra) of several different copolymer samples and a modelling based on Density Functional Theory calculations and semiempirical calculations on suitable model molecules.

Enhanced flow injection analysis for measurements of S-nitrosothiols species in biological samples using highly selective amperometric nitric oxide sensor

A highly selective nitric oxide (NO) sensor is fabricated and applied to devise an enhanced flow injection analysis (FIA) system for S-nitrosothiols (RSNOs) measurement in biological samples. The NO sensor is prepared using a polytetrafluoroethylene (PTFE) gas-permeable membrane loaded with Teflon AF (R) solution, a copolymer of tetrafluoroethylene and 2,2-bis(trifluoroethylene)-4,5-difluoro-1,3-dioxole, to improve selectivity. This method is much simpler and possesses good performance over a wide range of RSNOs concentrations. Standard deviation for three parallel measurements of blood plasma is 4.0%. The use of the gas sensing configuration as the detector enhances selectivity of the FIA measurement vs. using less selective electrochemical detectors that do not use PTFE/Teflon type outer membranes.

Ultrafast chemistry of nanoenergetic materials studied by time-resolved infrared spectroscopy: Aluminum nanoparticles in teflon

Ultrafast mid-infrared (IR) spectroscopy is used to monitor chemical reactions initiated by flash-heating a nanoenergetic material consisting of 30 nm diameter Al nanoparticle fuel in a Teflon(AF) oxidizer. Teflon(AF) is a copolymer of tetrafluoroethylene (TFE) and 2,2-bis(trifluoromethyl)-4,5-difluoro-1,3-dioxole (dioxole), so Al can react with several different moieties. Transitions associated with CF2 stretching of TFE or CFO stretching or CF3 stretching of dioxole were monitored. The reactions of Al with CFO occurred with time constant (k(1))(-1) = 50 (+/- 20 ps); reactions of Al with CF2 or CF3 were more than 10 times slower, (k(2))(-1) = 0.7 (+/- 0.05 ns). An interesting frequency oscillation is seen in the 1148 cm(-1) band, where the peak frequency undergoes a time-dependent shift from 1148 to 1155 cm(-1) and then back to 1148 cm(-1). Due to the coincidence of CFO and CF2 stretching transitions, this band in the copolymer represents an amalgamated vibration with amplitude on both TFE and dioxole. As concentration is varied from pure dioxole to pure TFE, the band blue-shifts. A kinetic scheme and a model for the concentration dependence of the amalgamated vibration frequency are developed, which show that the frequency oscillation is a consequence of the arrangement of reactants on the nanoscale, which creates two types of oxidizer. The type adjacent to the Al nanoparticle is in a region of high local fuel concentration, while the other type is too distant from the fuel to react.

Highly efficient cyclization of o-iodobenzoates with aldehydes catalyzed by cobalt bidentate phosphine complexes: A novel entry to chiral phthalides

Methyl 2-iodobenzoates 1a-c undergo cyclization reactions with various aromatic aldehydes 2 a-m (RC6H4CHO: R=H 2a, 4-CH3 2b, 4-tBu 2 c, 4-OMe 2 d, 3-OMe 2 e, 4-Cl 2 f, 4-CF3 2g, 4-CN 2h, 4-Ph 2i; benzo[d][1,3]dioxole-5-carbaldehyde (2j), -napthaldehyde (2k), benzofuran-2-carbaldehyde (21), and isonicotinaldehyde (2m)) in the presence of [CoI2(dppe)] (dppe = 1,2-bis(diphenylphosphino)ethane) and Zn powder in dry THF at 75 degrees C for 24 h to give the corresponding phthalide derivatives 3a-m and 3q-t in good to excellent yields. Under similar reaction conditions, less reactive aliphatic aldehydes, heptanal (2n), butyraldehyde (2o), and 2-phenylacetaldehyde (2p) also underwent cyclization reactions with la to provide 3n-p, respectively, in fair to good yields. The catalytic reaction can be further extended to cinnamyl aldehyde (2q) with la to give the corresponding phthalide derivative 3u. This synthetic method is compatible with a variety of functional groups on the aryl ring of 2. The high efficiency of the cobalt catalyst containing a dppe (dppe=1,2-bis(diphenylphosphino)ethane) ligand encouraged us to investigate the asymmetric version of the present catalytic reaction by employing bidentate chiral ligands. Thus, aromatic aldehydes 2a-c, 2f, and 2g undergo cyclization with 2-iodobenzoate (1a) smoothly in the presence of [CoI2(S,S)-dipamp}] ((SS)-dipamp(1S,2S)-(+)-bis[2-methoxyphenyl]phenylphosphino)ethane) and zinc powder in THF at 75 degrees C for 24 h, giving the corresponding (S)-phthalides 4a-e in 81-89% yields with 70-98% ee. A possible mechanism for the present catalytic reaction is proposed.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 29390-67-8, you can contact me at any time and look forward to more communication. Product Details of 29390-67-8.

Effect of amorphous fluorinated coatings on photocatalytic properties of anodized titanium surfaces

The photocatalytic activity promoted by anodized titanium surfaces coated with different amorphous perfluoropolymers was evaluated. A copolymer between tetrafluoroethylene and perfluoro-4-trifluoromethoxy-1,3-dioxole and two perfluoropolyethers containing ammonium phosphate and triethoxysilane functionalities, respectively, were tested as coating materials. These coatings revealed good adhesion to the anodized titanium substrate and conferred to it both hydrophobicity and oleophobicity. The photocatalytic activity of the coating on anodized titanium was evaluated by monitoring the degradation of stearic acid via Infrared spectroscopy. The degradation rate of stearic acid was reduced but not set to zero by the presence of the fluorinated coatings, leading to the development of advanced functional coatings. The morphological variations of the coatings as a result of photocatalysis were also determined by atomic force microscopy. (C) 2013 Elsevier B. V. All rights reserved.

Polymers based on a novel 1,3-perfluorodioxole for use as a soft polymer pellicle in 157nm lithography

A series of copolymers of tetrafluoroethylene and 4-trifluormethoxy-1,3-perfluorodioxole (TFETFMD) were prepared as well as a homopolymer of the dioxole (TEMD) using various free-radical initiators. The copolymers were characterized by F-19 NMR, TGA, DSC and VUV measurements. The transparency at 157nm increased with increasing dioxole content reaching an alpha (mum(-1)) = 0.76 for an unoptimized homopolymer of the dioxole prepared with a perfluorinated peroxide initiator. Exposure studies of the dioxole homopolymer at 157 nm indicate rapid formation of carbonyl species and therefore an anticipated short lifetime as a potential polymer pellicle for 157 nm lithography.
