    The synthesis of 2,4,6-triiodoisophthalamides substituted by a lactam moiety is described. A tandem ring opening-ring closure methodology consisting of a regiospecific ether cleavage of the tetrahydrofuroanilide 14b, followed by lactamization to α-oxygenated anilides 15b or 16b, gave α-O-functionalized-δ-valerolactams 12b or 13b, respectively. This approach is also compatible with the presence of ester
