substituted phenols in the presence of (diacetoxyiodo)benzene promotes the formation of a phenoxenium ion, a very electrophilic species able to react with various nucleophiles leading rapidly to a plethora of different cores present in natural products via several novel oxidative processes. This strategy fits within the concept of ‘aromatic ring umpolung’; in this paper a personal account by our laboratory
