We describe here a strategy to improve the expression efficiency and enantioselectivity of Aspergillus niger epoxide hydrolase (ANEH) by directed evolution. Based on a blue-colony screening system using the LacZalpha (beta-galactosidase alpha peptide) complementation solubility reporter, several ANEH variants out of 15000 transformants from a random-mutagenesis library were identified that show improved recombinant expression in E. coli. Among them, Pro221Ser was subsequently used as a template for iterative saturation mutagenesis (ISM) at sites around the ANEH binding pocket. Following four rounds of ISM, a highly enantioselective mutant was identified that catalyzes the hydrolytic kinetic resolution of racemic glycidyl phenyl ether with a selectivity factor of E=160 in favor of the (S)-diol compared to WT ANEH characterized by E=4.6. Expression of this mutant is 50 times higher than that of WT ANEH. It also serves as an excellent stereoselective catalyst in the hydrolytic kinetic resolution and desymmetrization of several other structurally diverse epoxides. Copyright

A method for the synthesis of new chiral alpha/beta-dimethylamino esters and beta-amino ethers from (S,S)-hydrobenzoin is described. These new O,N-donor ligands are expected to prove a useful platform for exploring the relationship between the ligand structure and stereoselective direct aldol condensation catalyzed by their lanthanide complexes. The initial survey of the catalytic utility of newly synthesized complexes in the unique aldol-Tishchenko reaction of aldehydes and aliphatic ketones is also presented.

However, they have proven to be challenging because of the mutual inactivation of both catalysts. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 19132-06-0

The invention relates to a method for converting a precatalyst complex to an active catalyst complex, wherein the precatalyst complex and the active catalyst complex comprise a ruthenium atom and an optically active ligand that is insoluble in water, and the active catalyst complex furthermore comprises a monohydride and a water molecule. The method comprises the steps of providing water as an activation solvent system with a pH value equal or below 2, and solving said precatalyst complex, an acid, and hydrogen therein. The invention further relates to a method for manufacturing a catalyst composition, a method for hydrogenating a substrate molecule and a reaction mixture.

Future efforts will undeniably focus on the diversification of the new catalytic transformations. These may comprise an expansion of the substrate scope from aromatic and heteroaromatic compounds to other hydrocarbons. Keep reading other articles of 4254-15-3! Synthetic Route of 4254-15-3

Application of 4254-15-3, In homogeneous catalysis, catalysts are in the same phase as the reactants. A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes. 4254-15-3, Name is (S)-Propane-1,2-diol, molecular formula is C3H8O2. belongs to chiral-oxygen-ligands compounds. In a Article，once mentioned of 4254-15-3

Compounds structurally related to 2-cyclohexen-1-one 1,4-di-O-benzyl-L-threitol ketal were prepared and subjected to the Simmons-Smith cyclopropanation.From these experiments a mechanistic model for diastereoselective cyclopropanation of common ring systems (five-, six-, and seven-membered) has been formulated.Diastereoselectivity is thought to result from preferential chelation of the Simmons-Smith reagent at the least sterically hindered lone pair of electrons on the dioxolane oxygen proximal to the alkene.It is found that the presence of oxygen atoms in the dioxolane appendages provide sites for competitive chelation of the reagent, which can antagonize the diastereoselection due to chelation at dioxolane oxygen.That chelation by dioxolane oxygen does occur and is responsible for diastereoselectivity is inferred from studies with a hydrocarbon model system.Surprisingly, both dioxolane appendages are shown to be necessary for optimum diastereoselection since, under the conditions of the Simmons-Smith cyclopropanation, 2-cycloalken-1-one ethylene ketals are reversibly ring opened to zwitterionic intermediates.
