three-step synthetic route to α-ketoaldehydes starting from aryl aldehydes is reported. The aldehydes were treated with iPrMgCl and iodoform to obtain β-diiodoalcohols, which were then oxidized with o-iodoxybenzoicacid at room temperature to the corresponding β-diiodoketones. Subsequent reaction of the β-diiodoketone to the α-ketoaldehyde occurred under oxygen transfer from dimethyl sulfoxide. These sensitive
