Palladium-Catalyzed Carbonylative Coupling of Aryl Iodides and Benzyl Acetylenes to 3-Alkylidenefuran-2-ones under Mild Conditions and Its Density Functional Theory Modeling
A general and efficient method for the palladium‐catalyzed carbonylativecoupling of aryliodides to benzylacetylenes has been developed. Various furanones have been prepared in excellent yields from their corresponding benzylacetylenes at room temperature under a CO atmosphere. For aliphatic alkynes, their corresponding alkynones were obtained in good yields. Detailed DFT calculations have also

A general, efficient and practical method for the synthesis of 3-alkylidenefuran-2-ones has been developed from readily accessible aryl iodides and benzyl acetylenes via a recyclable palladium-catalyzedcarbonylative coupling reaction in a green solvent 2-MeTHF. The reaction proceeds smoothly under a CO atmosphere and mild conditions, yielding a wide range of furanones in good to excellent yields.

stereoselective synthesis of E-3-(arylidene)-5-(alkyl/aryl)-2(3H)-furanones was developed. The methodology features regioselective addition of β-aryl acrylic acids to iodoacetylenes to furnish the Z-acyloxy iodoalkenes. A stereoselective 5-exo-trig Mizoroki–Heck reaction of the acyloxy iodoalkenes generates the target E-2(3H)-furanones. The approach was applied in a formal synthesis of the naturally
