Synthesis of Substituted Furans by Palladium-Catalyzed Cyclization of Acetylenic Ketones

Fukuda, Yukitoshi,Shiragami, Hiroshi,Utimoto, Kiitiro,Nozaki, Hitosi

, p. 5816 - 5819 (1991)

Palladium-catalyzed cyclization of β,γ-acetylenic ketones gives furans by intramolecular oxypalladation and subsequent protodemetalation. 3-Allylfurans were exclusively obtained by trapping the intermediate 3-furylpalladium species with allyl halides in t
