Computational tools for enzyme improvement: why everyone can ? and should ? use them

This review presents computational methods that experimentalists can readily use to create smart libraries for enzyme engineering and to obtain insights into protein?substrate complexes. Computational tools have the reputation of being hard to use and inaccurate compared to experimental methods in enzyme engineering, yet they are essential to probe datasets of ever-increasing size and complexity. In recent years, bioinformatics groups have made a huge leap forward in providing user-friendly interfaces and accurate algorithms for experimentalists. These methods guide efficient experimental planning and allow the enzyme engineer to rationalize time and resources. Computational tools nevertheless face challenges in the realm of transient modern technology.

Visible-Light-Promoted Redox Neutral ?,?-Difluoroallylation of Cycloketone Oxime Ethers with Trifluoromethyl Alkenes via C-C and C-F Bond Cleavage

A visible-light-promoted redox neutral ?,?-difluoroallylation of cycloketone oxime ethers with trifluoromethyl alkenes through C-C and C-F bond cleavage has been achieved, which affords various cyano-substituted gem-difluoroalkenes in generally good yields. The reaction provides a facile protocol for forming gem-difluoroalkene functionality and a cyano group while incorporating them into one molecule. The conversion of the resulting cyano-substituted gem-difluoroalkenes to cyclic monofluoroalkenes via a second C-F bond cleavage was also described.

Chemistry is traditionally divided into organic and inorganic chemistry. SDS of cas: 453-20-3, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 453-20-3

The pure rotational spectra of succinic, itaconic, and methylsuccinic anhydrides were collected in the region of 7?18 GHz using Fourier transform microwave spectroscopy. Each molecule shows varying degrees of puckering, demonstrating the effects of substitution on torsional and bond angle strain. The spectra of all three molecules exhibit perturbations consistent with internal motion; succinic and itaconic anhydride display pseudorotational motion (DeltaE = 0.1 cm?1 and 0.2 cm?1, respectively), while methylsuccinic anhydride shows two uncoupled vibrations (DeltaE01 = 0.4 cm?1 and DeltaE02 = 1.2 cm?1). Analyses of similar five-membered rings demonstrate the relationship between the planarity of the ring and the barrier to pseudorotation.

In heterogeneous catalysis, the catalyst is in a different phase from the reactants. Quality Control of 3-Hydroxytetrahydrofuran, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 453-20-3, name is 3-Hydroxytetrahydrofuran. In an article，Which mentioned a new discovery about 453-20-3

1,4-Butanediol can be produced from 1,4-anhydroerythritol through the co-catalysis of monometallic mixed catalysts (ReOx/CeO2+ReOx/C) in the one-pot reduction with H2. The highest yield of 1,4-butanediol was over 80 %, which is similar to the value obtained over ReOx?Au/CeO2+ReOx/C catalysts. Mixed catalysts of CeO2+ReOx/C showed almost the same performance, giving 89 % yield of 1,4-butanediol. The reactivity trends of possible intermediates suggest that the reaction mechanism over ReOx/CeO2+ReOx/C is similar to that over ReOx?Au/CeO2+ReOx/C: deoxydehydration (DODH) of 1,4-anhydroerythritol to 2,5-dihydrofuran over ReOx species on the CeO2 support with the promotion of H2 activation by ReOx/C, isomerization of 2,5-dihydrofuran to 2,3-dihydrofuran catalyzed by ReOx on the C support, hydration of 2,3-dihydrofuran catalyzed by C, and hydrogenation to 1,4-butanediol catalyzed by ReOx/C. The reaction order of conversion of 1,4-anhydroerythritol with respect to H2 pressure is almost zero and this indicates that the rate-determining step is the formation of 2,5-dihydrofuran from the coordinated substrate with reduced Re in the DODH step. The activity of ReOx/CeO2+ReOx/C is higher than that of ReOx?Au/CeO2+ReOx/C, which is probably related to the reducibility of ReOx/C and the mobility of the Re species between the supports. High-valent Re species such as Re7+ on the CeO2 and C supports are mobile in the solvent; however, low-valent Re species, including metallic Re species, have much lower mobility. Metallic Re and cationic low-valent Re species with high reducibility and low mobility can be present on the carbon support as a trigger for H2 activation and promoter of the reduction of Re species on CeO2. The presence of noble metals such as Au can enhance the reducibility through the activation of H2 molecules on the noble metal and the formation of spilt-over hydrogen over noble metal/CeO2, as indicated by H2 temperature-programmed reduction. The higher reducibility of ReOx?Au/CeO2 lowers the DODH activity of ReOx?Au/CeO2+ReOx/C in comparison with ReOx/CeO2+ReOx/C by restricting the movement of Re species from C to CeO2.

Catalytic Friedel-Crafts Reactions on Saturated Heterocycles and Small Rings for sp3-sp2 Coupling of Medicinally Relevant Fragments

gem-Diarylheterocycles display a wide range of biological activity. Here we present a systematic study into the formation of 4- to 6-membered O- and N-heterocycles and cyclobutanes bearing the diaryl motif through a catalytic Friedel?Crafts reaction from the corresponding benzylic alcohols. 3,3-Diaryltetrahydrofurans, 4,4-diaryltetrahydropyrans, 3,3-diarylpyrrolidines, 4,4-diaryl-piperidines, as well as diarylcyclobutanes are examined, with results for 3,3-diaryloxetanes and 3,3-diarylazetidines presented for comparison. Three catalytic systems are investigated for each substrate [Ca(II), Li(I) and Fe(III)], across preinstalled aromatic groups of differing electronic character. In most cases examined, the diaryl product is obtained directly from the alcohol with good yields using the most appropriate catalyst system. In the absence of a nucleophile, the olefins from the 5- and 6-membered substrates by elimination of water are obtained under the same reaction conditions.
