Abstract

A simple method has been developed for the synthesis of a type of bridged heterocycles using tetraynes. The strategy uses 1,3-diphenylisobenzofuran or 2,5-diphenylfuran and tetraynes as substrates and reactions proceed through an HDDA–[4+2] adduct. Products are obtained in moderate to good yield.
