摘要

Abstract 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 BCl 3. 2- Substituted 3-iodobenzo [b] furans were synthesized and transformed into 2, 3- ...
