; Oiarbide, Mikel; Palomo, Claudio (Royal Society of Chemistry, 2023) Artículo / Artikulua

Aminocatalytic asymmetric conjugate addition of aldehydes to Michael acceptors is a well established C-C bond forming methodology. However, various acrylic-type acceptors, including acrylic acid derivatives and acrolein, ...

Enantioselective addition of alkynyl ketones to nitroolefins assisted by Brønsted base/H-bonding catalysis

Various sets of enolizable alkynyl ketones (including methyl ynones with α-aryl, α-alkenyl, and α-alkoxy groups) were able to react smoothly with nitroolefins with the assistance of bifunctional Brønsted base/H-bond catalysts ...

Organocatalytic Michael addition of unactivated a-branched nitroalkanes to afford optically active tertiary nitrocompounds

Lorea Revilla, Beñat; García-Urricelqui, Ane; Odriozola Ibarguren, José Manuel

; Palomo, Claudio (ACS, 2023) Artículo / Artikulua

The direct, asymmetric conjugate addition of unactivated ¿-branched nitroalkanes is developed based on the combined use of chiral amine/ureidoaminal bifunctional catalysts and a tunable acrylate template to provide tertiary ...

α-Hydroxy ketones as masked ester donors in Brønsted base catalyzed conjugate additions to nitroalkenes

Olaizola, Iurre; Campano, Teresa E.; Iriarte, Igor; Vera, Silvia; Mielgo, Antonia; García Castillo, Jesús María

; Odriozola Ibarguren, José Manuel

; Oiarbide, Mikel; Palomo, Claudio (Wiley, 2018) Artículo / Artikulua

The catalyst-controlled enantioselective direct addition reaction of enolizable esters and related carboxylic acid derivatives to p electrophiles remains a difficult synthetic transformation. In this study, the suitability ...
