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 ; Odriozola Ibarguren, José Manuel ; Palomo, Claudio (Wiley, 2016)
Artículo / Artikulua
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; García Castillo, Jesús María ; González Guerrero, Alberto ; Odriozola Ibarguren, José Manuel ; Bañuelos, Patricia ; Linden, Anthony (ARKAT USA, Inc., 2005)
Artículo / Artikulua
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 ; Razkin Lizarraga, Jesús; Lorea Revilla, Beñat; Mielgo, Antonia; García Castillo, Jesús María ; 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 ; García Castillo, Jesús María ; Oiarbide, Mikel; Palomo, Claudio (Wiley, 2019)
Artículo / Artikulua
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 ; Razkin Lizarraga, Jesús; Espinal Viguri, Maialen ; Oiarbide, Mikel; Mielgo, Antonia; García Castillo, Jesús María ; 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 ...
