Palladium-Catalyzed Carbonylative Cyclization of β-Bromo-α,β-Unsaturated Ketones Leading to Alkylidenefuranones
摘要:
beta-Bromo-alpha,beta-unsaturated ketones are carbonylatively cyclized to (Z)-alkylidenefuranones in good yields under carbon monoxide pressure in DMF in the presence of a catalytic amount of a palladium catalyst along with Et(3)N.
