A New Synthetic Route to 2,5-Dihydrofurans
Dulcere, Jean-Pierre,Baret, Nathalie,Rodriguez, Jean
, p. 303 - 304 (1994)
ButOK-dimethyl sulfoxide-catalysed selective isomerization of 3-methylene tetrahydrofurans 1 provides a new convenient route to 2,5-dihydrofuran 2 precursors of furan-2(3H)-ones 8 or furans 4 or 9.
Dimerization of butenolide structures. A biomimetic approach to the dimeric sesquiterpene lactones (±)-biatractylolide and (±)- biepiasterolide
Bagal, Sharanjeet K.,Adlington, Robert M.,Baldwin, Jack E.,Marquez, Rodolfo
, p. 9100 - 9108 (2007/10/03)
The biomimetic synthesis of the bisesquiterpene lactones (±)-biatractylolide 1 and (±)-biepiasterolide 2 via dimerization of the captodative stabilized radical 8 is reported. Atractylon 7 has also been shown to be a possible intermediate during the biosynthesis of biatractylolide 1, biepiasterolide 2, atractylolide 3, and hydroxyatractylolide 4.
Preparation of α-Hydroxy-γ-lactones and their Application in the Synthesis of α,β-Butenolides, α-Alkylidene-γ-lactones and Furans
Munoz, A. Heber,Tamariz, Joaquin,Jimenez, Rogelio,Mora, Gustavo Garcia de la
, p. 501 - 522 (2007/10/02)
A straightforward synthesis of α-hydroxy-γ-butyrolactones was carried out by condensation reaction of the lithium anion of ethoxyethyl-protected cyanohydrins with epoxides, followed by acidic treatment.Synthetic applications of these synthons in the preparation of interesting α,β-butenolides, α-alkylidene-γ-lactones and furans are described.
