Ligand-Free Pd-Catalyzed Synthesis of 3-Allylbenzofurans by Merging Decarboxylative Allylation and Nucleophilic Cyclization

A new single Pd-catalyzed decarboxylative allylation-nucleophilic cyclization relay is reported by using α-alkynyl arylols and vinylethylene carbonates (or vinyl carbamates), and a wide range of 3-...
