The α-hydroxy carbonyl moiety is an important structural unit that is widely found in drug molecules, natural products and as a potentially valuable synthetic intermediate in organic and medicinal chemistry.Due to this, there have been many reports of synthetic methodologies for the construction of α-hydroxy carbonyl compounds.However, in these transformations, few methods have been developed for direct oxidation of olefins approach to α-hydroxy ketones,due to the difficulty in introducing two oxygen atoms concurrently and oxidizing selectively.Molecule iodine as an old reagentas has been widely used in organic synthesis for various organic functional group conversions due to its various functionalizing abilities and low cost, nontoxicity and easy availability.Over the past few years, iodine-catalysed reactions have been increasingly explored.In particular, the molecule iodine activation of carbon-carbon double bonds has received widespread interest in recent years.In general, initial activation of the n-bond can be achieved either through a charge transfer complex or via an iodoniurr/iodonium intermediate.
