Abstract
A detailed study of the heteroannulation of o-iodophenol with acetylenic substrates through palladium–copper catalysis leading to the synthesis of the 2-substituted benzofurans 21–29 is reported. An acylic compound 30 has been isolated and proved to be an intermediate in the synthesis of the benzofurans. Some of the benzofurans have been transformed into biologically active compounds.
