The Suzuki coupling reaction between alkynylboronic esters (generated in situ from acetylenic derivatives) and aryl bromides, pyridyl bromides or vinyl bromides is reported. 5-endo-dig-iodocyclisation of o-alkynylanisoles, generated by this palladium-catalyzed Suzuki coupling reaction, was performed with N-iodosuccinimide (NIS) in the presence of BCl3. 2-Substituted 3-iodobenzo[b]furans were synthesized and transformed into 2,3-disubstituted benzo[b]furans by Suzuki coupling reactions in high yields.
