Abstract

Nickel(II) complexes with chiral chelating nitrogen ligands such as 2,2'-bipyridines, 1,10-phenanthrolines and 1,2-diamino compounds are satisfactory catalysts for the Michael addition of nitromethane to benzalacetone, chalcone and 2-cyclohexenone. Only the catalytic system derived from Ni(acac)₂ and (+)-(S)-2-(anilinomethyl)pyrrolidine gave both good catalytic activity and asymmetric induction up to 24%.

Novel cyclic β-aminophosphonate derivatives as efficient organocatalysts for the asymmetric Michael addition reactions of ketones to nitrostyrenes
2010, Tetrahedron Asymmetry
Three novel catalysts based upon cyclic β-aminophosphonate derivatives 1–3 were designed to catalyze the asymmetric Michael addition reactions of ketones to β-nitrostyrenes. Among the catalysts that have been prepared in this study, cyclic β-aminophosphonic acid monoethylester 3 showed the highest catalytic ability, giving the corresponding Michael adduct in good yields, high enantioselectivities (up to 92% ee), and high diastereoselectivities (syn:anti up to 95:5).
Catalytic activation of nucleophile precursors with metal acetates in alcohol media and applications to enantioselective Michael addition reactions
2008, Tetrahedron Letters
Nickel(II) acetate tetrahydrate works as catalyst to activate nucleophile precursors in Michael addition reactions. Use of alcohol media is essential for the high catalytic activation of nucleophile precursors. Catalytic enantioselective reactions using a chiral nickel(II) acetate tetrahydrate between dimedone and α,β-unsaturated amide acceptors provide a useful synthetic access to enantiomers of enol lactones through the carbon-carbon bond formation.
Chiral pyridine-containing ligands in asymmetric catalysis
2007, Coordination Chemistry Reviews
In this article, an overview of the investigations on chiral py-containing ligands in asymmetric catalysis that have carrried out in the past years is provided. The ligands are divided into different types based on the number of pyridine moieties present and the way they are connected in the ligands, namely monopyridine, dipyridine (two pyridines connected by a bridge), bipyridine, phen(1,10-phenanthroline), terpyridine and oligopyridine. In each section, the synthetic strategies for each type of ligands are discussed and representative examples are given. Selected important results in asymmetric catalysis are mentioned.

Asymmetric Michael addition of silyl nitronates to cyclic α,β-unsaturated ketones catalyzed by chiral quaternary ammonium bifluorides: Isolation and selective functionalization of enol silyl ethers of optically active γ-nitro ketones
2006, Tetrahedron Letters
Highly enantioselective Michael addition of silyl nitronates to cyclic α,β-unsaturated ketones has been accomplished by the utilization of N-spiro C₂-symmetric chiral quaternary ammonium bifluoride 1 as an efficient catalyst, offering a new route to the enol silyl ethers of optically active γ-nitro ketones. The synthetic utility of this transformation has been demonstrated by the diastereoselective derivatizations of the optically active enol silyl ethers to the corresponding α-substituted cyclic ketones having three consecutive stereochemically defined stereocenters.
An ionic liquid influenced L-proline catalysed asymmetric Michael addition of ketones to nitrostyrene
2005, Journal of Molecular Catalysis A: Chemical
l-Proline in ionic liquid was employed for Michael addition of ketones to nitrostyrene. Optically active γ-nitroketones were obtained in good yields up to 80%. The reaction offers high syn selectivity (90%). The most striking feature is that the ionic liquid has been found to enhance the enantioselectivity, wherein enantiomeric excess approaches 75%. The system of ionic liquid and catalyst has proved to be an efficient recyclable medium.
