An efficient method for total syntheses of avenaciolide and isoavenaciolide via tungsten-pi-allyl complexes

[[abstract]]Total syntheses of avenaciolide and isoavenaciolide were achieved in six and three steps respectively based on starting chloropropargyl derivatives; the key step in such syntheses involves intramolecular alkoxycarbonylation of tungsten-eta(1)-propargyl complexes.[[fileno]]2010327010037[[department]]化學
