The condensation of an -hydroxy ketone with an aldehyde and ammonium acetate in the presence of diacetoxy iodoben- zene (DIB) produced the corresponding imidazole in excellent yield. ... Hypervalent iodine-mediated organic syntheses have at- tracted considerable attention in recent years.1 Various organo- iodide(III) reagents have successfully been utilized in different organic transformations. Recently, we applied diacetoxy iodo- benzene (DIB) for the synthesis of ...
