The Synthesis of 2,7-Dioxabicyclo[3.2.1]Octanes

Abstract Intramolecular acetals are prevalent in natural products including frontalin, exo and endo-brevicomin and other insect pheromones.1 Recently, a substituted 2,7-dioxabicyclo[3.2.1]-octane was employed as an intermediate in the total synthesis of the insect poison dl-pederamide.2 In this paper we wish to report on an efficient synthesis of 2,7-dioxabicyclo[3.2.1]octanes.
