title: Synthesis of natural products containing spiroketals via intramolecular hydrogen abstraction.
abstract: Although known for over a quarter of a century, the oxidative radical cyclisation route to spiroketals has found limited use in natural product synthesis in comparison to classical approaches. Its successful application in this field of research forms the subject of this perspective.
