Functionalization of enamides under Heck conditions has been limited to those with unsubstituted vinyl groups. By tuning reaction parameters that allow for the balance between stability and reactivity of reactants, the oxidative Heck cross-coupling to produce highly substituted enamides in good to excellent yields was achieved (see scheme).

Qualitative and quantitative NMR experiments were performed on 5M aqueous solutions of monoethanolamine (MEA) loaded with CO2 (alpha = 0.4) and in presence of 1mM FeSO4 x 7H2O as a catalyst. The main degradation products were identified and quantified by 1D and 2D NMR Spectroscopy as: N-(2-hydroxyethyl) imidazole (HEI), 2-oxazolidone (OZD), N-(2-hydroxyethyl) formamide (HEF). There are also some other signals not quantified yet because of the low intensity. The NMR results were compared with GC/LC-MS results of the same solution.

alpha-N-Acylamino acids have been developed as useful reagents for the preparation of optically pure alpha-aminoalkylaryl ketones.Protection of the amino group as either the ethoxycarbonyl or benzenesulfonyl derivative allows alanine to serve as an effective educt for the chirally specific synthesis of a variety of structures containing the phenylethylamine backbone.Benzene undergoes Friedel-Crafts acylation with the N-acylalanine acid chloride.Catalyst complexation with oxagenated aromatics, however, prohibits acylation of aryl ethers.An arylmetallo reaction scheme overcomes this problem and also affords regiospecificity not attainable in conventional acylations.As examples, optically pure ephedrines and amphetamines were directly synthesized without recourse to resolution since the chirality of the amino acid educt was entirely conserved throughout the process.

Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.Read on for other articles about 16251-45-9

Leukotriene biosynthesis inhibitors have potential as new therapies for asthma and inflammatory diseases. The recently disclosed thiopyrano[2,3,4- cd]indole class of 5-lipoxygenase (5-LO) inhibitors has been investigated with particular emphasis on the side chain bearing the acidic functionality. The SAR studies have shown that the inclusion of a heteroatom (O or S) in conjunction with an alpha-ethyl substituted acid leads to inhibitors of improved potency. The most potent inhibitor prepared contains a 2-ethoxybutanoic acid side chain. This compound, 14d (2-[2-[1-(4-chlorobenzyl)-4-methyl-6-[(5- phenylpyridin-2-yl)methoxy]-4,5-dihydro-1H-thiopyrano[2,3,4-cd]indol-2- yl]ethoxy]butanoic acid, L-699,333), inhibits 5-HPETE production by human 5- LO and LTB4 biosynthesis by human PMN leukocytes and human whole blood (IC50s of 22 nM, 7 nM and 3.8 muM, respectively). The racemic acid 14d has been shown to be functionally active in a rat pleurisy model (inhibition of LTB4, ED50 = 0.65 mg/kg, 6 h pretreatment) and in the hyperreactive rat model of antigen-induced dyspnea (50% inhibition at 2 and 4 h pretreatment; 0.5 mg/kg po). In addition, 14d shows excellent functional activity against antigen-induced bronchoconstriction in the conscious squirrel monkey [89% inhibition of the increase in R(L) and 68% inhibition in the decrease in C(dyn) (0.1 mg/kg, n = 3)] and in the conscious sheep models of asthma (iv infusion at 2.5 mug/kg/min). Acid 14d is highly selective as an inhibitor of 5-LO activity when compared to the inhibition of human 15-LO, porcine 12-LO and ram seminal vesicle cyclooxygenase (IC50 > 5 muM) or competition in a FLAP binding assay (IC50 > 10 muM). Resolution of 14d affords 14g, the most potent diastereomer, which inhibits the 5-HPETE production of human 5-LO and LTB4 biosynthesis of human PMN leukocytes and human whole blood with IC50s of 8 nM, 4 nM, and 1 muM respectively. The in vitro and in vivo profile of 14d is comparable to that of MK-0591, which has showed biochemical efficacy in inhibiting ex vivo LTB4 biosynthesis and urinary LTE4 excretion in clinical trials.

The effect of tethering a thioether to a rhodium(II) paddlewheel complex are evaluated in Si?H insertion reactions. This study provides further evidence for the benefits of incorporating thioethers into the rhodium paddlewheel motif. When using a tethered complex, the in situ carbenoid formation and subsequent Si?H insertion are not impeded, yields are improved by up to 12 % at elevated temperatures, and selectivity for diazo compounds is greater when compared to non-tethered catalysts. Computational modelling of the complexes is also presented in order to rationalize the results.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

In a recent study, we have shown by NMR spectrocopy that monoalkylcarbonates are formed in substantial amounts in aqueous solutions of the tertiary alkanolamine methyldiethanolamine (MDEA) upon loading with carbon dioxide (CO2). These species had been overlooked by most authors previously. In the present work, this study was extended to the primary alkanolamine monoethanolamine (MEA). Also here monoalkylcarbonates were found, but only at CO2 loadings above 0.5 mol CO2 per mol MEA. Both the amine and its carbamate form monoalkylcarbonates. The concentration of the monoalkylcarbonates was determined with 13C NMR spectroscopy in a wide range of CO2 loadings, MEA concentrations, and temperatures. Based on this comprehensive data the chemical equilibirium constants of the formation of the monoalkylcarbonates were determined.

Several grass and broadleaf weed species around the world have evolved multiple-herbicide resistance at alarmingly increasing rates. Research on the biochemical and molecular resistance mechanisms of multiple-resistant weed populations indicate a prevalence of herbicide metabolism catalyzed by enzyme systems such as cytochrome P450 monooxygenases and glutathione S-transferases and, to a lesser extent, by glucosyl transferases. A symposium was conducted to gain an understanding of the current state of research on metabolic resistance mechanisms in weed species that pose major management problems around the world. These topics, as well as future directions of investigations that were identified in the symposium, are summarized herein. In addition, the latest information on selected topics such as the role of safeners in inducing crop tolerance to herbicides, selectivity to clomazone, glyphosate metabolism in crops and weeds, and bioactivation of natural molecules is reviewed.

The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules.Read on for other articles about 1192-07-0Related Products of 1192-07-0
