Abstract
An important feature of this chemistry is the functionalization of the position next to the hydroxyl group to obtain 3-substituted hydroxyquinones 2. This functionalization can be achieved by different methodologies, [2] but a most effective one involves the use of phenyliodonium ylides 3. The latter, most easily prepared from the corresponding hydroxyquinones 1 and diacetoxyiodobenzene, [3] react with a variety of nucleophiles to afford 4, in an internal S ...
