Chiral Ti(IV) complexes of hexadentate Schiff bases as precatalysts for the asymmetric addition of TMSCN to aldehydes and the ring opening of cyclohexene oxide

Chiral dinuclear titanium(IV) complexes (generated in situ from hexadentate Schiff bases and titanium tetra-isopropoxide) have been found to be more effective catalysts for the asymmetric addition of trimethylsilyl cyanide to aldehydes and the ring openin

Enantioselective cyanosilylation of aldehydes catalyzed by novel camphor derived Schiff bases-titanium(IV) complexes

Five tridentate Schiff bases have been prepared from (1R,2S,3R,4S)-3-amino- 1,7,7-trimethylbicyclo[2.2.1]heptan-2-ol and salicylaldehydes. X-ray structure investigation revealed differences in their molecular conformation, and their titanium(IV) complexes

Synthesis, characterization and catalytic property of chiral oxo-vanadium (+)-pseudoephedrine complex supported on magnetic nanoparticles Fe3O4 in the cyanosilylation of carbonyl compounds

Vanadium complex of pseudoephedrine immobilized on magnetic nanoparticle Fe3O4[VO(Pseudoephedrine)@MNPs] was prepared and characterized by UV-vis, SEM, XRD, TGA, EDX, FT-IR, AGFM and elemental analysis techniques. VO(Pseudoephedrine)

The synthesis of tetradentate salens derived from (3R,4R)-N-substituted-3, 4-diaminopyrrolidines and their application in the enantioselective trimethylsilylcyanation of aromatic aldehydes

The in situ formed Ti(IV) complexes of pyrrolidine-based chiral salen ligands derived from natural l-tartaric acid were evaluated as catalysts in the enantioselective trimethylsilylcyanation of aromatic aldehydes. The different activity and selectivity of the catalysts in the formation of the products were found to be dependent on the N-substituent of the pyrrolidine.

Enantioselective cyanosilylation of ketones with amino acid/BINAP/ ruthenium(II)-lithium phenoxide catalyst systems

Enantioselective reactions of simple ketones, α,α- and β,β-dialkoxy ketones, and α-alkoxy ketones with trimethylsilyl cyanide catalyzed by the bimetallic systems of amino acid/BINAP/ruthenium(II) complexes and lithium phenoxide have been studied [BINAP=2,

Enantioselective cyanation of aldehydes catalyzed by bifunctional salen-aluminum complex

Chiral N-oxide salen ligands and their corresponding Al complexes were synthesized. Notably, the catalytic activity and asymmetric induction ability of the bifunctional N-oxide salen-Al for asymmetric cyanosilylation were compared with that of bi-componen

Fine modification of salen ligands - Effects on the salen-Ti-catalyzed asymmetric cyanosilylation of aldehydes

New bifunctional N-oxide salen-TiIV complexes and a pyrrolidine salen-TiIV complex in combination with achiral N-oxide were developed and applied to the asymmetric addition of trimethylsilyl cyanide to aldehydes. Notably, both enanti

A practical Ti-salen catalyst based on dimeric salen ligand for asymmetric addition of trimethylsilyl cyanide to aldehydes

A dimeric salen ligand derived from L-tartaric acid was synthesized through linking two salen units with 1,6-dibromohexane. The corresponding Ti complex was proved to be an efficient catalyst for asymmetric addition of trimethylsilyl cyanide to aldehydes,

CYANATION CATALYST AND METHOD FOR PRODUCING OPTICALLY ACTIVE CYANHYDRIN COMPOUND USING THE SAME

The present invention can provide a cyanation catalyst represented by the general formula (I): (in the formula (I), R1 through R4 are each an optionally substituted hydrocarbon group; R1 and R2 and/or R3 and R4 may form an optionally substituted carbon chain ring; R5 through R8 are each a hydrogen atom, or an optionally substituted hydrocarbon group; R5 and R6 and/or R7 and R8 may form an optionally substituted carbon chain ring; R9 and R10 are each a hydrogen atom, or an optionally substituted hydrocarbon group; W, X and Y each represent an optionally substituted binding chain; X and/or Y may be non-existent; M represents a metal or a metal ion; and ligands of M may each be located at any position).
