Gold-catalyzed addition of β-ketoesters to alkenes: Influence of electronic and steric effects in the reaction outcome
(Molecular Diversity Preservation International, 2018-03)
The gold-catalyzed intermolecular hydroalkylation of olefins with β-ketoesters represents a conceptually attractive and useful synthetic tool; however, it has been scarcely applied, remaining a challenge for chemists. The ...
Clean transesterification of β-ketoesters catalyzed by hybrid silica sol-gel
(Elsevier, 2006)
A mild chemoselective and suitable transesterification on b-ketoesters has been developed employing functionalized silica sol-gel as heterogeneous catalyst which can be reused several times without appreciable loss of ...
Chemo- and stereoselective reduction of β-keto esters by spores and various morphological forms of Mucor rouxii
(Elsevier Science Inc, 2002-05)
We report the efficient enantioselective reduction of a number of β-ketoesters by mycelial and yeast-like forms of the dimorphic fungus Mucor rouxii in a whole-cell process. Mycelial cells, grown in aerobiosis, were efficient ...
Síntese de furanos trissubstituídos via reações de oxopaladação aeróbica
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2019-02-25)
Furans are important heterocyclics with broad application in synthesis as a building block, frequently presented in a wide range of compounds that exhibit biological activity, including natural products. Intramolecular ...
Synthesis of 4H-chromenes promoted by NbCl<inf>5</inf> through multicomponent reaction
(2015-06-25)
Abstract Multicomponent reactions between phenols, β-ketoesters, and benzaldehydes for the synthesis of 4H-chromenes derivatives promoted by niobium pentachloride (NbCl<inf>5</inf>) were carried out, providing good yields ...
