Synthesis of substituted butenolides by the ring closing metathesis of two electron deficient olefins: a general route to the natural products of paraconic acids class
Selvakumar,Kalyan Kumar,Chandra Shekar Reddy,Chandra Chary
, p. 2021 - 2024 (2007)
A variety of allyl acrylates possessing electron-withdrawing groups undergo RCM using the second generation Grubbs' catalyst in the presence of a Lewis acid resulting in diverse butenolides in high isolated yields. This methodology provides a general rout
"On water" catalytic enantioselective sulfenylation of deconjugated butyrolactams
Singha Roy, Soumya Jyoti,Mukherjee, Santanu
, p. 6921 - 6925 (2017/09/01)
The first catalytic enantioselective α-sulfenylation of deconjugated butyrolactams has been developed using dimeric cinchona alkaloids as catalysts in a water-enriched reaction medium. Highly substituted and densely functionalized γ-lactams, bearing a qua
Unsaturated lactones: Synthesis and applications
Yu,Kayser
, p. 1583 - 1588 (2007/10/02)
An easy approach to the synthesis of substituted unsaturated lactones is described, and the reactions of these compounds with nucleophiles leading to the formation of useful intermediates are reported.
Synthesis of 3-Ethoxycarbonyl-3-buten-4-olides and 3-Ethoxycarbonyl-4-butanolides
Gaudemar-Bardone, Francoise,Mladenova, Margarita,Couffignal, Rene
, p. 1043 - 1047 (2007/10/02)
This paper describes a synthesis of 3-acyl-2-alkyl-3-ethoxycarbonylpropanoic acids from ethyl 2-oxoalkanoates and 2-bromoalkanoic acids.These acids are cyclised via intramolecular dehydratation to give 2,4-dialkyl-3-ethoxycarbonyl-3-buten-4-olides or are
SYNTHESE DE β-ETHOXYCARBONYL γ-LACTONES
Gaudemar-Bardone, F.,Mladenova, M.,Couffignal, R.
, p. 1047 - 1048 (2007/10/02)
β-ethoxycarbonyl β, γ-insaturated γ-lactones 2 are easily prepared by dehydration of β-acyl β-ethoxycarbonyl α-alkyl propionic acids.Otherwise the condensation of these acids with allylzinc reagents produces β-ethoxycarbonyl γ-lactones 3 with a β-ethyleni
