Palladium-catalyzed cyclization reaction of allylic bromides with 1,2-dienyl ketones. An efficient synthesis of 3-allylic polysubstituted furans
3-Allylic polysubstituted furans were synthesized via a palladium-catalyzed cyclization reaction of allylic bromides with differently substituted 1,2-allenyl ketones. This process may occur via the reaction of a furanyl palladium intermediate with allylic bromide.
