Abstract

A new stereocontrolled route to conjugated dienynes is described, utilising organometallic addition to pyrylium salts followed by Wittig homologation and dehydrohalogenation. The utility of this methodology is illustrated in the first total synthesis of the marine metabolite Carduusyne A.
