Organocatalytic enantioselective conjugate addition of aldehydes to maleimides in deep eutectic solvents
Flores-Ferrándiz, Jesús,Chinchilla, Rafael
, p. 302 - 306 (2017)
The conjugate enantioselective addition of aldehydes, mainly α,α-disubstituted, to maleimides leading to enantioenriched succinimides, has been achieved in recyclable deep eutectic solvents at room temperature. Enantiomerically pure carbamate-monoprotecte
Solvent-induced reversal of enantioselectivity in the synthesis of succinimides by the addition of aldehydes to maleimides catalysed by carbamate-monoprotected 1,2-diamines
Flores-Ferrndiz, Jess,Fiser, Bla,Gmez-Bengoa, Enrique,Chinchilla, Rafael
, p. 1218 - 1225 (2015/03/04)
A simple change in the polarity of the solvent allows both enantiomers of substituted succinimides to be obtained in the enantioselective conjugate addition reaction of aldehydes, mainly disubstituted, to maleimides catalysed by chiral carbamate-monoprote
Highly enantioselective michael addition promoted by a new diterpene-derived bifunctional thiourea catalyst: A doubly stereocontrolled approach to chiral succinimide derivatives

, p. 121 - 127 (2014/03/21)
A doubly stereocontrolled organocatalytic asymmetric Michael addition to the synthesis of substituted succinimides is described. Starting from aldehydes and maleimides, both enantiomers of the succinimides could be obtained in high to excellent yields (up
Enantioselective synthesis of succinimides by Michael addition of aldehydes to maleimides organocatalyzed by chiral primary amine-guanidines

, p. 5085 - 5092 (2013/11/06)
The monoguanylation of (1S,2S)- and (1R,2R)-cyclohexane-1,2-diamine affords chiral primary amine-guanidines that are used as chiral organocatalysts in the enantioselective Michael addition of aldehydes, particularly α,α-disubstituted aldehydes, to maleimi
Enantioselective Michael addition of aldehydes to maleimides organocatalysed by chiral 1,2-diamines: An experimental and theoretical study
Avila, Angel,Chinchilla, Rafael,Gomez-Bengoa, Enrique,Najera, Carmen
, p. 1531 - 1535 (2013/12/04)
Simple and commercially available chiral 1,2-diamines were used as organocatalysts for the enantioselective conjugate addition of aldehydes, including α,α-disubstituted, to maleimides. The reaction was carried out in the presence of hexanedioic acid as an
A highly efficient large-scale asymmetric Michael addition of isobutyraldehyde to maleimides promoted by a novel multifunctional thiourea

experimental part, p. 1740 - 1748 (2012/01/03)
A novel class of chiral multifunctional thioureas bearing a chiral lipophilic beyerane scaffold and a primary amino group were designed and prepared. The thioureas were proven to be effective for catalyzing the asymmetric Michael addition between isobutyr
