Corrosion protection of mild steel in hydrochloric acid solutions in presence of 5-(Benzyloxy)indole – Monte Carlo simulation, weight loss and electrochemical studies

The inhibition effects of 5-(Benzyloxy)indole, noted 5BI on mild steel corrosion in 1.0 M HCl were studied with potentiodynamic polarization, electrochemical impedance spectroscopy techniques and weight loss studies. It was shown that 5BI act as good corrosion inhibitor for mild steel protection. The high inhibition efficiencies were attributed to the simple blocking effect by adsorption of inhibitor molecules on the steel surface. Molecular dynamics was carried out to establish mechanism of corrosion inhibition for mild steel with 5BI in acidic medium. The inhibition action of the compound was assumed to occur via adsorption on the steel surface through the active centers in the molecule following Langmuir isotherm model. The results indicated that the corrosion inhibition is due to the physical and chemical adsorption on the steel surface.

Enantioselective synthesis of structurally intricate and complementary polyoxygenated building blocks of spongistatin 1 (altohyrtin a)

Enantioselective approaches to the construction of four complex building blocks of the structurally intricate marine macrolide known as spongistatin 1 are presented. The first phase of the synthetic effort relies on a practical approach to a desymmetrized, enantiomerically pure spiroketal ring system incorporating rings A and B. Concurrently, the C17-C28 subunit, which houses one-fifth of the stereogenic centers of the target in the form of rings C and D, was assembled via a composite of stereocontrolled aldol condensations. Once arrival at the entire C1-C28 sector had been realized, routes were devised to provide two additional highly functionalized sectors consisting of C29-C44 and C38-C51. A series of subsequent transformations including cyclization of the E ring and hydroboration to afford the B-alkyl intermediate for the key Suzuki coupling to append the side chain took advantage of efficient stereocontrol. Ultimately, complete assembly and functionalization of the western EF sector of spongistatin was thwarted by an inoperative Suzuki coupling step intended to join the side chain to the C29-C44 sector, and later because of complications due to protecting groups, which precluded the complete elaboration of the late stage C29-C51 intermediate.

Molecular structure and spectral properties of indolenine based norsquaraines versus squaraines

Novel indolenine based norsquaraine dyes, wherein the oxygen of the squaric acid bridge was substituted with a barbituric or a dicyanomethylene group, were synthesized and their molecular structure, spectral and luminescent properties were compared to those of analogous squaraine dyes. The molecular structure was investigated using X-ray analysis, NMR spectroscopy and ab initio DFT B3LYP/6-311G (d, p) simulations. The calculated populations of possible conformers and the barriers of internal rotations were found to be in good agreement with the experimental data. Norsquaraines absorb and emitt light within the same long-wavelength spectral range as the corresponding squaraines but due to intramolecular H-bonds and increased conformational rigidity they were less sensitive to solvent polarity and the presence of protein (BSA).

Direct oxidative C-P bond formation of indoles with dialkyl phosphites

The direct phosphonation of indoles was developed. In this reaction, dialkyl phosphites and indoles were used as substrates, and the C-P bond was formed through oxidative coupling mediated by silver(I) acetate. Various indoles and different dialkyl phosphites were effective substrates for the reaction, and dialkylphosphoryl-substituted indoles were obtained in up to 71% yield.

Endophyte-mediated adjustments in host morphology and physiology and effects on host fitness traits in grasses

Endophytic fungi have been shown to increase tolerance of hosts to biotic and abiotic stresses and in some cases alter growth and development of plants. In this article we evaluate some effects that clavicipitaceous endophytes have on development and physiology of plant tissues. We postulate that oxidative stress protection is the fundamental underlying benefit conferred by many endophytes, accounting for frequently observed enhanced disease resistance, drought tolerance, heavy metal tolerance and tolerance to numerous additional oxidative stresses. We hypothesize that endophyte-mediated oxidative stress protection of the host is the result of at least two processes, including: (1) secretion of reactive oxygen species (ROS) from endophytic mycelia into plant cells; and (2) secretion of auxin from endophytic mycelia into plant cells. Both processes result in an increase in ROS in plant tissues; and stimulate plant tissues to increase activities of antioxidant systems. Auxin is suggested to function in suppression of plant cell death and may be important in maintaining the endophyte-plant symbiosis.

Br¡ãnsted acid-promoted formation of stabilized silylium ions for catalytic friedel-crafts C-H silylation

A counterintuitive approach to electrophilic aromatic substitution with silicon electrophiles is disclosed. A strong Br¡ãnsted acid that would usually promote the reverse reaction, i.e., protodesilylation, was found to initiate the C-H silylation of electron-rich (hetero)arenes with hydrosilanes. Protonation of the hydrosilane followed by liberation of dihydrogen is key to success, fulfilling two purposes: to generate the stabilized silylium ion and to remove the proton released from the Wheland intermediate.

Improving the stability of photochromic fluorinated indolylfulgides

Fluorinated indolylfulgides are a class of photochromic organic compounds. It is possible to consider potential applications of these compounds in optical devices such as switches and memory. Two novel fulgides, a deuterated trifluoromethyl indolylfulgide and a trifluoromethyl dicyclopropyl indolylfulgide, were designed based on prior mechanistic studies to have greater thermal stability and potentially greater photochemical stability. The absorption spectra, thermal stabilities in both toluene and polymer films, and photochemical fatigue resistances of both fulgides were measured. The cyclizable Z-form. of the dicyclopropyl fulgide displayed a significant red shift of the absorption maximum compared to any other fulgide. Deuteration led to greater thermal stability of the fluorinated fulgide. Moreover, the Z-form of the dicyclopropyl fulgide showed excellent durability in PMMA at 80C. The solution-based study of the dicyclopropyl fulgide demonstrated only E-Z-isomerization after prolonged treatment (380 h) at 80C in toluene. In addition, the trifluoromethyl dicyclopropyl indolylfulgide is the most photochemically stable yet reported; it underwent 10,000 photochemical cycles, coloration followed by bleaching, before degrading by 13%.

Structure-activity relationships of galabioside derivatives as inhibitors of E. coli and S. suis adhesins: Nanomolar inhibitors of S. suis adhesins

Four collections of Galalpha1-4Gal derivatives were synthesised and evaluated as inhibitors of the PapG class II adhesin of uropathogenic Escherichia coli and of the PN and PO adhesins of Streptococcus suis strains. Galabiosides carrying aromatic structures at Cl, methoxyphenyl O-galabiosides in particular, were identified as potent inhibitors of the PapG adhesin. Phenylurea derivatisation at C3? and methoxymethylation at O2? of galabiose provided inhibitors of the S. suis strains type PN adhesin with remarkably high affinities (30 and 50 nM, respectively). In addition, quantitative structure-activity relationship models for E. coli PapG adhesin and S. suis adhesin type PO were developed using multivariate data analysis. The inhibitory lead structures constitute an advancement towards high-affinity inhibitors as potential anti-adhesion therapeutic agents targeting bacterial infections.

Electrochemical Synthesis of Hindered Primary and Secondary Amines via Proton-Coupled Electron Transfer

Accessing hindered amines, particularly primary amines alpha to a fully substituted carbon center, is synthetically challenging. We report an electrochemical method to access such hindered amines starting from benchtop-stable iminium salts and cyanoheteroarenes. A wide variety of substituted heterocycles (pyridine, pyrimidine, pyrazine, purine, azaindole) can be utilized in the cross-coupling reaction, including those substituted with a halide, trifluoromethyl, ester, amide, or ether group, a heterocycle, or an unprotected alcohol or alkyne. Mechanistic insight based on DFT data, as well as cyclic voltammetry and NMR spectroscopy, suggests that a proton-coupled electron-transfer mechanism is operational as part of a hetero-biradical cross-coupling of alpha-amino radicals and radicals derived from cyanoheteroarenes.
