Abstract
The 5-endo-dig-iodocyclization of o-alkynylphenols with iodine in the presence of NaHCO3 at room temperature produces functionalised 2-substituted-3-iodobenzo[b]furans, which are useful synthetic intermediates for the preparation of 2,3-disubstituted benzo[b]furans via palladium-catalysed reactions.Keywords
