title: Combining two-directional synthesis and tandem reactions: synthesis of trioxadispiroketals.
abstract: A tandem bromonium ion-promoted cyclization of two pendant hydroxyl groups onto a central furan core provides a highly direct route to both the [5,5,5]- and the [6,5,6]-trioxadispiroketal ring systems.
