Abstract
InCl3-catalyzed propargylation of indoles and phenols was developed. A strategy combining propargylation with intramolecular cyclization was used to easily prepare 2-benzyl-3-arylbenzofurans and -naphthofurans, which are important pharmaceutical intermediates.
Key words
Friedel-Crafts alkylation - propargylation - cyclization - benzofuran - InCl3
