Rodriguez, Arantxa and Moran, Wesley J. (2011) Furan synthesis through AuCl3-catalysed cycloisomerisation of β-alkynyl β-ketoesters. Tetrahedron Letters, 52 (20). pp. 2605-2607. ISSN 0040-4039
Abstract

AuCl3 efficiently catalyses the cycloisomerisation of readily available β-alkynyl β-ketoesters to generate trisubstituted furans. The substrate scope is wide and the reaction is high yielding and operationally simple.
