Chiral Room Temperature Ionic Liquids as Enantioselective Promoters for the Asymmetric Aldol Reaction
Wiley Online Library (2014)Chiral ionic liquids derived from natural amino acids are shown to be green and efficient media for direct asymmetric aldol reactions at room temperature catalyzed by (S)-proline. The corresponding aldol products were ... -
Competition versus Cooperation in Catalytic Hydrogelators for anti-Selective Mannich Reaction
Wiley (2017-07-21)Chemical systems find similarities in different sociological and biological processes, in which the entities compete or cooperate for a favorable outcome. The structural and functional adaptations leading to emergent ... -
Rational Design of Simple Organocatalysts for the HSiCl3 Enantioselective Reduction of (E)-N-(1-Phenylethylidene)aniline
MDPI (2021-11-18)Prolinamides are well-known organocatalysts for the HSiCl3 reduction of imines; however, custom design of catalysts is based on trial-and-error experiments. In this work, we have used a combination of computational ... -
Structural insight into the aggregation of L-prolyl dipeptides and its effect on organocatalytic performance
Royal Society of Chemistry (2015)NMR and organocatalytic studies of four dipeptides derived from L-proline are described. Results indicate that important conformational changes around the catalytic L-proline moiety are observed for free dipeptides upon ...
