Abstract

o-Iodocardanol, readily available from cardanol by iodination­, has been used to prepare a variety of lipophilic benzo[b]furans. 2-Substituted benzo[b]furans have been prepared by a Sonogashira cross-coupling/cyclization process. 2,3-Disubstituted benzo[b]furans have been obtained from o-alkynylcardanols by an oxypalladation/reductive elimination process.
