Journal ArticleDOI
A highly efficient solvent-free asymmetric direct aldol reaction organocatalyzed by recoverable (S)-binam-L-prolinamides. ESI-MS evidence of the enamine-iminium formation.
TL;DR: The aldol reaction has been studied by the use of positive ESI-MS technique, providing the evidence of the formation of the corresponding enamine-iminium intermediates.
Journal ArticleDOI
Solvent-free asymmetric direct aldol reactions organocatalysed by recoverable (Sa)-binam-l-prolinamide
TL;DR: In this article, the combination of (Sa)-binam- l -Pro (5 ǫ ) and benzoic acid (10 Ã 0 ) was used as catalysts in the direct aldol reaction between different aliphatic ketones and 4-nitrobenzaldehyde under solvent-free reaction conditions.

N-Tosyl-(Sa)-binam-L-prolinamide as highly efficient bifunctional organocatalyst for the general enantioselective solvent-free aldol reaction
TL;DR: In this article, the authors presented a study supported by the Direccion General de Investigación of the Ministerio de Educación y Ciencia of Spain (DGDE) and the University of Alicante (GRJ06-05).
Journal ArticleDOI
Enantioselective direct aldol reaction of α-keto esters catalyzed by (Sa)-binam-D-prolinamide under quasi solvent-free conditions
Santiago F. Viózquez,Abraham Banon‐Caballero,Gabriela Guillena,Carmen Nájera,Enrique Gómez-Bengoa +4 more
TL;DR: (S(a))-Binam-D-prolinamide is an efficient organocatalyst for the direct aldol reaction between α-keto esters as electrophiles and alkyl and α-functionalised ketones, under quasi solvent-free conditions, providing access to highly functionalised chiral quaternary α-hydroxyesters with up to 92% ee.
