Enantioselective Michael Addition of Water [PDF]

Chemistry – A European Journal, 2014
AbstractThe enantioselective Michael addition using water as both nucleophile and solvent has to date proved beyond the ability of synthetic chemists. Herein, the direct, enantioselective Michael addition of water in water to prepare important β‐hydroxy carbonyl compounds using whole cells of Rhodococcus strains is described.

The Phospha‐Michael Addition in Organic Synthesis [PDF]

European Journal of Organic Chemistry, 2005
AbstractPhosphorus is essential for many reagents in organic synthesis, for ligands of late‐transition metals and for phosphono‐ and phosphanylamino acids, the latter being important isosteres of amino acids. Similar to the Michaelis–Arbuzov and the Michaelis–Becker reaction the phospha‐Michael addition, i. e.

Deciphering the roles of multiple additives in organocatalyzed Michael additions

Chemical Communications, 2016
The synergistic effects of multiple additives (water and acetic acid) on the asymmetric Michael addition of acetone to nitrostyrene catalyzed by primary amine-thioureas (PAT) were precisely determined.

Organocatalytic Asymmetric Aza-Michael Additions

Chemistry - A European Journal, 2009
AbstractThe catalytic aza‐Michael addition is an important reaction within synthetic organic chemistry, given the significance of the biologically and synthetically interesting products, such as β‐amino acids and β‐lactams. In the last decade organocatalysis emerged as a powerful tool in asymmetric synthesis and had a large impact on the development of

Rotaxanes via Michael Addition

Organic Letters, 2000
[reaction: see text] The application of a template effect to the classical Michael addition of heteronucleophiles to various Michael acceptor systems leads in good yields to a new trapping synthesis of [2]rotaxanes with conjugated functional groups in their axles.

Michael additions of benzoins versus Michael-Stetter additions of aldehydes

Tetrahedron Letters, 1980
Abstract Triethylamine catalyzed Michael additions of benzoins to chalcone can prevail over the expected Michael-Stetter additions when certain thiazolium ion conjugate bases - prepared in situ from the pertinent thiazolium salts and triethylamine- are used as catalysts.
