Palladium-catalyzed synthesis of lipophilic benzo[a]furans from cardanol

Article abstract of DOI:10.1055/s-2007-965939

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.
