The electronic states of isothiazole studied by VUV absorption spectroscopy and ab initio configuration interaction methods

The isothiazole VUV absorption spectrum over the range 5-12 eV shows (broad) intense bands centred near 5.17, 6.11, 7.37, 7.75, 9.18 and 10.43 eV. The lowest Rydberg states relating to the first ionisation energy are difficult to identify, but higher members are particularly numerous on the region from 8.4 to 9.6 eV. Electronic excitation energies for valence (singlet and triplet) and Rydberg-type states have been computed using ab initio multi-reference multi-root CI methods. These studies used a triple zeta + double polarisation basis set, augmented by diffuse (Rydberg) orbitals. The theoretical study shows the nature of the more intense Rydberg state types, and positions of the main valence and Rydberg bands. By study of the excitation energies to specific upper states, the vertical ionisation energies (IE) are confirmed as pi4- 1 < pi3- 1 < sigma18- 1 (LPN) < sigma17- 1 (LPS). Structures for the pi- and sigma-cations, and the (neutral) pipi*-triplet states have been obtained. Calculated energies for low-lying Rydberg states are close to those observed, and there is generally a good correlation between the theoretical intensities and the experimental envelope. The ground state atomic and molecular properties are in good agreement with experiment. The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

Synthetically useful reactions of thiophenes arid benzolb]thiophenes are reviewed in which the aromatzcity of the thiophene ring is lost either permanently or temporarilyj i.e. so-called “non-benzenoid” reactions. These include cyclcaddition reactions with arynes, hetarynes, carbenes, nitrsnes, olefins, acetylenes, ketones, and other substrates and various ring-opening reactions, e.g. of organometallic derivatives and 2-Aminothiophenes. Also reviewed are C-2 protonation and reactions of thiophenes at the sulprtur atom, e.g. alkylation.

Utility of Complementary Molecular Reactivity and Molecular Recognition (CMR/R) Technology and Polymer-Supported Reagents in the Solution-Phase Synthesis of Heterocyclic Carboxamides

The use of our recently reported chemical library purification strategy in the development of a herbicidal lead, N-(3-benzoylphenyl)-3-(1,1-dimethylethyl)-1-methyl-1H-pyrazole-5-carboxamide (3), is described. The approach applying fundamental properties of complementary molecular reactivity and molecular recognition (CMR/R) as the basis for a general purification strategy was utilized. Polymeric reagents were used in the synthesis to generate reactive species involved in product formation, and complementary molecular reactivity/molecular recognition polymer 8 (CMR/R polymer 8) was used in the solution-phase syntheses of building blocks, primary libraries, and lead refinement libraries. An extension of the CMR/R methodology was applied, utilizing a sequestration enabling reagent (SER), transforming a reactant into an electrophilic species sequestrable by CMR/R polymer 8. This library purification strategy enabled rapid lead generation and lead refinement to afford herbicide 27o. The CMR/R solid-phase purification technique enabled a simple, general, and powerful protocol, eliminating the usual tedious and time-consuming methods required for solution-phase product purification. The result was the synthesis of hundreds of compounds, prepared in a relatively short time, leading to a compound with a 4-fold improvement in herbicidal activity over the initial lead.

Screening of yeasts isolated from Baijiu environments for 2-phenylethanol production and optimization of production conditions

2-Phenylethanol (2-PE) with a pleasant rose-like odor is a valuable aroma compound used in many fields. 2-PE production by yeast is considered a promising alternative to chemical synthesis and extraction from natural materials. In this report, the strain YF1702 produced a significantly higher level of 2-PE when compared with other strains isolated from Baijiu-producing environments. According to morphological properties, physiological and biochemical characteristics, and 26S rDNA sequence analysis, strain YF1702 was identified as Pichia kudriavzevii. The optimal fermentation conditions of YF1702 for producing 2-PE were obtained by single-factor experiments, Plackett?Burman design, steepest ascent design, and response surface methodology. The optimal inoculation conditions for strain YF1702 were 50?g/L glucose, 6.0?g/L yeast extract, 10.7?g/L L-Phe, and 32?g/L Tween-60. The optimal fermentation conditions were pH 2.3, 26?C, 210?rpm shaking, an inoculum size of 0.4% (v/v), and a loading volume of 25.5?mL/250?mL for 56?h. Under these optimal conditions 2-PE production by YF1702 was 5.09?g/L. This strain has the potential to increase the content of 2-PE in Baijiu production and enhance the aroma characteristics of Baijiu.

Aerogel from chemo-enzymatically oxidized fenugreek gum: an innovative delivery system of isothiazolinones biocides

Aerogels of chemo-enzymatically oxidized, lyophilized fenugreek gum (EOLFG) were evaluated as ?delivery system? (DS) of the microbiocide mix 5-chloro-2-methyl-4-isothiazolin-3-one (CIT) and 2-methyl-4-isothiazolin-3-one (MIT). These biocides have a broad activity spectrum and a low MIC (minimal inhibitory concentration) in the ppm range. They are approved under the EU Biocidal Product Directive for various applications, including cosmetics, are classified as skin sensitizers, and are under increasing scrutiny to limit or eliminate their use. We demonstrate that CIT/MIT can be uptaken into EOLFG aerogel corks by immersion into aqueous solutions of microbiocides, followed by blotting and re-lyophilization to generate ?loaded? EOLFG aerogels. Incubation of ?loaded? corks in water brings about a slow and almost complete release of the absorbed actives having the same MIC of free biocides against selected bacterial pathogens. This new biomaterial could represent an innovative DS of microbiocides and other actives for a variety of industrial, food, cosmetic, and biomedical applications.
