Practical catalytic cross-coupling of secondary alkyl electrophiles with secondary alkyl nucleophiles under Cu catalysis has been realized. The use of TMEDA and LiOMe is critical for the success of the reaction. This cross-coupling reaction occurs via an SN2 mechanism with inversion of configuration and therefore provides a general approach for the stereocontrolled formation of C-C bonds between two tertiary carbons from chiral secondary alcohols.

Chemical engineers ensure the efficiency and safety of chemical processes, adapt the chemical make-up of products to meet environmental or economic needs, and apply new technologies to improve existing processes. Computed Properties of C4H10O2,

(Chemical Equation Presented) We have designed a series of diphosphite ligands to study the effect of the backbone, the size of the chelate ring, and the substituents of the biphenyl moieties and to determine the scope of this type of ligand in the Pd-catalyzed asymmetric substitution reactions of different types of substrates. Good-to-excellent activities and enantioselectivities have been obtained for disubstituted linear substrate 11 (TOF’s up to >2000 mol × (mol × h)-1, ee values up to 99%) and cyclic substrate 14 (TOF up to 285 mol × (mol × h) -1, ee values up to 92%). However, these ligands are inadequate for the Pd-catalyzed allylic alkylation of monosubstituted linear substrates because they provide low enantioselectivities.

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 24621-61-2Computed Properties of C4H10O2

Career opportunities within science and technology are seeing unprecedented growth across the world, and those who study chemistry or another natural science at university now have increasingly better career prospects. name: (2S,3S)-Butane-2,3-diol,

Stereoisomers of distinct chiral amino acids were observed to occur in L-enantioenriched form in carbonaceous chondrite meteorites. Meteoritic amines and monocarboxylic acids were recently shown to occur in racemic ratio. In this study we investigated the electronic circular dichroism and anisotropy spectra of chiral alcohols, chiral amines, and chiral monocarboxylic acids. We recorded circular dichroism and anisotropy spectra from 280 to 170 nm in aqueous solution using a synchrotron-radiation ultraviolet circular dichroism spectrophotometer. The obtained anisotropy spectra are employed to discuss the likely role of ultraviolet circularly polarized light leading to enantioenriched amino acids, as well as racemic amines and monocarboxylic acids during their primordial interstellar synthesis. These data will moreover accompany the European Space Agency’s Rosetta mission, which successfully landed Philae on the nucleus of comet 67P/Churyumov?Gerasimenko to search for chiral organic molecules.

Ruthenium complexes of phosphinoferrocenylaminophosphine ligands (BoPhoz ligands) have been prepared by combining the ligands with tris(triphenylphosphine)ruthenium dichloride and precipitating the complexes. The optimal species exhibit high enantioselectivities for the asymmetric hydrogenation of functionalized ketones, particularly beta-ketoesters.

The hydrolytic kinetic resolution (HKR) of terminal epoxides, using chiral chromium(III)-salen catalysts based on DIANANE (endo,endo-2,5-diaminonorbornane) , was studied. A broad substrate scope was found for the chromium(III)-DIANANE catalysts, and very low loadings (down to 0.05 mol%) were needed to achieve high enantiomeric purities of both the remaining epoxides and the product diols (up to >99% ee). Besides monosubstituted epoxides, 2-methyl-2-n-pentyloxirane, which is an example for 2,2-disubstituted epoxides, could be ring-opened in an asymmetric fashion with water in the presence of an electronically tuned chromium-(III)-DIANANE complex.

BACKGROUND: 2,3-Butanediol (2,3-BD) has a wide range of applications in chiral molecular synthesis, biofuel additives, and in food flavor additive manufacturing. Fermentation is a favorable method for 2,3-BD production. However, it requires much time and produces several NADH related byproducts which compete with 2,3-BD production. Bacillus subtilis has an excellent ability for 2,3-BD production by biocatalysis. However, its production is limited by low intracellular NADH and the reversible property of acetoin reductase (AR/2,3-BDH). The whole cell biocatalyst process with two different NADH regeneration systems was designed for efficient production of 2,3-BD in B. subtilis 168. RESULTS: Formate dehydrogenase and glucose dehydrogenase for NADH regeneration were successfully co-expressed with acetoin reductase in B. subtilis 168. After optimization of biocatalyst bioconversion conditions, B. subtilis 168/pMA5-bdhA-HpaII-fdh yielded 74.5 g L?1 of 2, 3-BD with 9.3 g L?1 h?1 productivity by fed batch and 115.4 g of 2,3-BD was achieved using same batch bacterium by three repeated batch bioconversions. On the other hand, 63.7 g L?1 of 2, 3-BD was produced with 7.92 g L?1 h?1 productivity by B. subtilis 168/pMA5-bdhA-HpaII-gdh. To our knowledge, the volume productivity obtained here is the highest ever reported for biocatalysis. CONCLUSION: A higher productivity of 2,3-BD from acetoin was achieved by whole cell biocatalysis with NADH regeneration systems in B. subtilis 168. This approach can be applied for NADH related bio-based chemicals production to improve titer, yield and productivity.
