Center stage: An oxidative Prins–pinacol tandemprocess mediated by a hypervalent iodine reagent has been accomplished. The strategy allows rapid access to highly functionalized spirocyclic cores (see scheme) present in many natural products. A first application to the formal synthesis of (−)‐platensimycin has been achieved.

oxidative version of the famous tandem process fits within the concept of “aromatic ring umpolung” and allows the stereoselective transformation of simple phenols into highly elaborated spirocyclicdienone cores containing several quaternary carbon centers. The scope and the limitations of this process, including the study of its stereoselectivity, are described in this article. As a direct application
