Oxidative bridgehead functionalization of (4 + 3) cycloadducts obtained from oxidopyridinium ions†
Abstract
Treatment of selected (4 + 3) cycloadducts derived from oxidopyridinium ions with N-iodosuccinimide (NIS) in hexafluoroisopropanol (HFIP) resulted in the formation of bridgehead ethers via a net oxidative C–H activation.
