Ready access to the 6,8-dioxabicyclo[3.2.1]octane ring system using asymmetric heterocycloaddition induced by a chiral sulfoxide: application to the total synthesis of the Mus musculus pheromone

摘要

A new stereocontrolled total synthesis of the (1R,5S,7R)-exo-6,8-dioxabicyclo[3.2.1]oct-3-ene skeleton of the Mus musculus pheromone has been achieved via an asymmetric intermolecular Diels-Alder reaction and an intramolecular conjugated addition, controlled by a chiral auxiliary.
