Enantioselective synthesis of (-)-exiguolide by iterative stereoselective dioxinone-directed prins cyclizations

Three become one: The title compound can be prepared in 26 steps by employing a unified Prins cyclization strategy to construct both tetrahydropyran rings (see scheme). The route combines two similar dioxinone fragments and one aldehyde component to gener
