A new synthesis of chrysin (1) and luteolin (4) was accomplished by the cyclodehydrogenation of the appropriately substituted 2'-hydroxychalcones 21 and 22 in the presence of iodosobenzene diacetate/potassium hydroxide in methanol.The scope and limitation of this transformation is discussed. - Keywords: Cyclodehydrogenation / 2'-Hydroxychalcones / Flavones / Iodosobenzene diacetate
