Domino Wittig Diels-Alder reaction: an expeditious entry into the AB ring system of furanosesquiterpenes

A domino Wittig Diels-Alder reaction has been employed in delineating a short and flexible synthetic stratagem for ready access to the AB ring system and the tricyclic framework of furanosesquiterpenes, such as the bioactive natural products, furodysin and furodysinin.
