Development of an α′-hydroxy enone for the aminocatalytic asymmetric formal conjugate addition of aldehydes to acrylates, vinyl ketones and acrolein
(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, ...
Organocatalytic Michael addition of unactivated a-branched nitroalkanes to afford optically active tertiary nitrocompounds
(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
(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 ...
Enantioselective addition of alkynyl ketones to nitroolefins assisted by Brønsted base/H-bonding catalysis
(Wiley, 2019)
info:eu-repo/semantics/article,
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 ...
