Abstract
Novel intermediates for non-ionic polyiodo amino-substituted benzenepolyamides having polyol substituents on the amide nitrogens are provided which are 5-amino-6-hydroxy-1,3-dioxepanes. The compounds provide an economic and efficient route to novel contrast media having excellent chemical and physiological properties. Also provided are methods for preparing the subject compounds.
