    • Asymmetric assembly of all‐carbon tertiary/quaternary nonadjacent stereocenters through organocatalytic conjugate addition of α‐cyanoacetates to a methacrylate equivalent 

      Iriarte, Igor; Vera, Silvia; Badiola, Eider; Mielgo, Antonia; Oiarbide, Mikel; García Castillo, Jesús María Upna Orcid; Odriozola Ibarguren, José Manuel Upna Orcid; Palomo, Claudio (Wiley, 2016)   Artículo / Artikulua  OpenAccess
      An efficient, highly diastereo- and enantioselective assembly of acyclic carbonyl fragments possessing nonadjacent all-carbon tertiary/quaternary stereoarrays is reported based on a Brønsted base catalyzed Michael ...
    • Asymmetric propionate aldol reactions of a chiral lithium enolate accessible from direct enolization with n-butyllithium 

      Palomo, Claudio; Oiarbide, Mikel; Gómez Bengoa, Enrique; Mielgo, Antonia; González Rego, María Concepción Upna; García Castillo, Jesús María Upna Orcid; González Guerrero, Alberto Upna; Odriozola Ibarguren, José Manuel Upna Orcid; Bañuelos, Patricia Upna; Linden, Anthony (ARKAT USA, Inc., 2005)   Artículo / Artikulua  OpenAccess
      The presented lithium enolate-based methodology is suitable for access to propionate syn-aldol motifs with high levels of stereocontrol. The reactive lithium enolate species is generated by direct treatment of a camphor-based ...
    • Development of an α′-hydroxy enone for the aminocatalytic asymmetric formal conjugate addition of aldehydes to acrylates, vinyl ketones and acrolein 

      Odriozola Ibarguren, José Manuel Upna Orcid; Razkin Lizarraga, Jesús; Lorea Revilla, Beñat; Mielgo, Antonia; García Castillo, Jesús María Upna Orcid; 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 

      Campano, Teresa E.; Iriarte, Igor; Olaizola, Olatz; Etxabe, Julen; Mielgo, Antonia; Ganboa, Iñaki; Odriozola Ibarguren, José Manuel Upna Orcid; García Castillo, Jesús María Upna Orcid; Oiarbide, Mikel; Palomo, Claudio (Wiley, 2019)   Artículo / Artikulua  OpenAccess
      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 Upna Orcid; Razkin Lizarraga, Jesús; Espinal Viguri, Maialen Upna Orcid; Oiarbide, Mikel; Mielgo, Antonia; García Castillo, Jesús María Upna Orcid; Palomo, Claudio (ACS, 2023)   Artículo / Artikulua  OpenAccess
      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 Upna Orcid; Odriozola Ibarguren, José Manuel Upna Orcid; Oiarbide, Mikel; Palomo, Claudio (Wiley, 2018)   Artículo / Artikulua  OpenAccess
      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 ...
