Pyrophosphoric acid ester compound, bisphosphate ester compound and catalyst

The invention pertains to a novel pyrophosphoric acid ester compound represented by formula (1) and a bisphosphoric acid ester compound represented by formula (2). In the formulas, R is an aryl group, organic silyl group, or halogen atom. These compounds can adequately activate carbonyl compounds, imine compounds, and the like due to having higher acidity than conventional phosphoric acid ester compounds. Usefulness as a metal ligand is also expected.

MANUFACTURING METHOD OF OPTICAL ACTIVE ALCOHOL

PROBLEM TO BE SOLVED: To provide a method for providing optical active alcohol capable of being a perfume material or a cold sensation raw material with high optical purity and high selectivity by conducting an asymmetric carbonyl-en ring closure reaction

Cationic Chiral Fluorinated Oxazaborolidines. More Potent, Second-Generation Catalysts for Highly Enantioselective Cycloaddition Reactions

The coordination of chiral ligands to Lewis acid metal derivatives, a useful strategy for enantioselective, electrophilic catalysis, generally leads to a lower level of catalytic activity than that of the original uncomplexed compound. Activation by furth

Chiral environment of catalytic sites in the chiral metal-organic frameworks

Chiral metal-organic frameworks are considered a useful platform in heterogeneous catalysis for enantioselective chemical transformations. However, it has been observed that the enantioselectivity is sensitive to the site at which the reaction takes place

The effect of host structure on the selectivity and mechanism of supramolecular catalysis of Prins cyclizations

The effect of host structure on the selectivity and mechanism of intramolecular Prins reactions is evaluated using K12Ga4L6 tetrahedral catalysts. The host structure was varied by modifying the structure of the chelating moieties and the size of the aromatic spacers. While variation in chelator substituents was generally observed to affect changes in rate but not selectivity, changing the host spacer afforded differences in efficiency and product diastereoselectivity. An extremely high number of turnovers (up to 840) was observed. Maximum rate accelerations were measured to be on the order of 105, which numbers among the largest magnitudes of transition state stabilization measured with a synthetic host-catalyst. Host/guest size effects were observed to play an important role in host-mediated enantioselectivity.

Chiral amide directed assembly of a diastereo- and enantiopure supramolecular host and its application to enantioselective catalysis of neutral substrates

The synthesis of a novel supramolecular tetrahedral assembly of K 12Ga4L6 stoichiometry is reported. The newly designed chiral ligand exhibits high diastereoselective control during cluster formation, leading exclusively t

ASYMMETRIC CYCLIZATION OF UNSATURATED ALDEHYDES CATALYZED BY A CHIRAL LEWIS ACID

A highly enantioselective cyclization of unsaturated aldehydes has been accomplished with the chiral zinc reagent 1 derived from dimethylzinc and (R)-(+)-1,1'-bi-2-naphthol.Thus, the Aldehyde 2 and 10 are treated with the reagent 1 producing the trans alcohol 3 and 11, respectively, with high optical purity (>90percent ee).In sharp contrast, the aldehyde 8 affords the totally racemic alcohol 9.Since the chiral zinc reagent 1 possesses its C2-symmetry, either enantiomer can be prepared from the unsaturated aldehyde by choosing the chiral ligand, (R)-(+)- or (S)-(-)-1,1'-bi-2-naphthol.
