A new complex of palladium-thiourea and carbon tetrabromide catalyzed carbonylative annulation of o-hydroxylarylacetylenes: efficient new synthetic technology for the synthesis of 2,3-disubstituted benzo[b]furans.

Abstract

[reaction: see text] A highly effective cocatalysis system (PdI2-thiourea and CBr4) was developed for carbonylative cyclization of both electron-rich and electron-deficient o-hydroxylarylacetylenes to the corresponding methyl benzo[b]furan-3-carboxylates.
