Chiral Zn(II)-bisamidine complex as a Lewis-Brønsted combined acid catalyst: application to asymmetric Mukaiyama aldol reactions of α-ketoesters.
Focusing on the steric and electronic properties of the resonance-stabilized amidine framework, a cationic metal-bisamidine complex was designed as a conjugated combined Lewis-Brønsted acid catalyst. The chiral Zn(II)-bisamidine catalyst prepared from the 2,2'-bipyridyl derived bisamidine ligand, ZnCl₂, and AgSbF₆ promoted asymmetric Mukaiyama aldol reaction of α-ketoester and α,α-disubstituted...
متن کاملPrimary amine-metal Lewis acid bifunctional catalysts: the application to asymmetric direct aldol reactions.
The first example of metal Lewis acid-primary amine bifunctional cooperative catalyst derived from primary amino acids was developed, and it was found to catalyze aldol reactions of cyclic ketones highly efficiently with very good to excellent stereoselectivities.
متن کاملDisulfonimide-catalyzed asymmetric vinylogous and bisvinylogous Mukaiyama aldol reactions.
The term vinylogy, which describes a unique property of p systems where the electron density and reactivity is amplified along conjugated bonds, was proposed 75 years ago by Fuson. The principle becomes particularly relevant in the context of the aldol reaction: While metal dienolates often furnish mixtures of aand g-addition products, the corresponding dienolsilanes react with high selectivity...
متن کاملBoric Acid-Functionalized Fe3O4@SiO2 as a Novel Superparamagnetically Recoverable Nano Catalyst for Mukaiyama-Aldol Reaction
We have reported the fabrication of boric acid incorporated into surface of magnetite nanoparticles. The catalyst was characterized using spectroscopic, magnetic and thermal techniques (FT-IR, SEM, XRD, ICP, VSM and TGA). It catalyzed Mukaiyama aldol reaction of a ketene silyl acetal type nucleophile ((1-methoxy-2-methylprop-1-enyloxy) trimethylsilane), and various aldehydes (aromatic, aliphati...
متن کاملChiral Lewis acid-catalyzed asymmetric Baylis-Hillman reactions.
An effective chiral Lewis acid-catalyzed asymmetric Baylis-Hillman reaction is described. Good to high enantioselectivities were obtained using 3 mol % chiral catalyst. Novel camphor-derived dimerized ligands were prepared from the condensation of (+)-ketopinic acid with the corresponding diamines and hydrazine under acidic conditions. When alpha-naphthyl acrylate was used as a Michael acceptor...
