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. Brief reference is made to thiophene I, l-dioxideu and attention is drawn to other littie-used reactions of thiophenes of potential synthetic usefulness, e.g. inverted reactivity of thienyl-lithium compounds.

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.

Effect of power level on the microwave pyrolysis of tire powder

The pyrolytic performance of tire powder treated under different specific microwave powers (SMP), powers per 1?g sample, (9, 15, and 24?W/g) was investigated. The experimental results show that the pyrolysis level of tire powder was enhanced with increasing SMP. The maximum yields of liquid product (45%) and gas product (18.5%) were obtained at 15 and 24?W/g, respectively. In addition, the conversion rates of main organic elements transferred to three-phase products were calculated. All of the evolved gases were collected in successive gasbags, and 80% of the volumes were low-molecular-weight gases like H2, CH4 and C2H4; the fraction of gases generated increased with increasing SMP. The liquid products contained a large amount of aromatic hydrocarbons, and more limonene (nearly 10%) was produced in microwave pyrolysis than in conventional pyrolysis of tires. The proximate and ultimate analyses of the solid product showed a slight difference in composition as a function of SMP. Furthermore, there may be a competitive reaction between the sulfur release to the volatiles and sulfur fixation, forming ZnS; the amount of ZnS varied with SMP. The energy recovery was examined, which provides a useful measure of the energy efficiency of microwave pyrolysis process.

Recent advances in computing heteroatom-rich five- and six-membered ring systems

Recent developments in computer technology and the increasing efficiency and accuracy of current ab initio and density functional programs allow the investigation of increasingly complex systems. Molecules that could be treated only at the semiempirical level ten years ago can now be computed at the density functional or the MP2 level with basis sets of double-zeta quality. Very often, these calculations are accurate enough to explain experimental findings, and consequently many experimental studies are augmented by quantum chemical calculations. However, in many cases just a few kilocalories per mole may decide between different reaction mechanisms, different explanations of physical effects, or even a preferred tautomer or conformer. Since the inherent errors of MP2 and DFT calculations are still significantly larger than chemical accuracy, high-level calculations are mandatory for many problems. This holds particularly true for the investigation of reaction barriers involving bond-breaking processes. Although these problems have been recognized by many investigators, a substantial number of papers lack sufficient accuracy. This accuracy problem appears to be more severe for heteroatom-rich species than for other systems, in particular for systems with adjacent heteroatoms. However, DFT calculations were found to cope surprisingly well with the geometric parameters of most of these systems. As is common in heterocyclic chemistry, many studies concern tautomeric equilibria. While quantum chemical calculations are straightforward for the question of the most stable isomer, experiments are sometimes very demanding. Therefore, quantum chemistry can easily provide answers that may require substantial experimental effort. Comparatively few studies concern the investigation of entire reaction paths. This is much more demanding than computing a limited number of tautomers, of course, but usually provides a very detailed picture of the reaction mechanism. In certain cases, it was only possible to judge the nature of a chemical reaction on the basis of quantum chemical calculations. Most studies concerning pyrimidines originate from biochemical questions. Since these systems are dominated by hydrogen-bonding and/or dispersion contributions, methods beyond the Hartree-Fock level are mandatory. The success of quantum chemical studies in this field is impressive and many effects could be explained on the basis of these theoretical investigations.
