, p. 527 - 538 (2007/10/03)
On treatment with base the pentynones 8a-f undergo anionic addition reactions of the resulting enolate species to the alkyne moiety and afford the 2,5-disubstituted furans 10a-f in yields ranging from 10-91%. The proposed mechanism involves the 2-methylen
STUDIES ON THE SYNTHESIS OF FURANS BY ANIONIC CYCLIZATION OF 4-PENTYNONES
Vieser, Ralf,Eberbach, Wolfgang
, p. 4405 - 4408 (2007/10/02)
The synthesis of 5-substituted 2-carbomethoxymethyl-furans 4 is achieved by base promoted cyclization of the 4-pentynones 3a-e which are easily accessible from the 4-pentynal 1.
