ABSTRACT:
Novel 1,6-diaza [4.4] spirodilactams having heterocyclic-containing substituents on each spiro ring nitrogen atom are produced by reaction of a heterocyclic-substituted primary amine compound and a spirodilactam precursor selected from 4-oxoheptanedioic acid compounds or 1,6-dioxaspiro[4.4]nonane-2,7-dione compounds. The substituted spirodilactam products have a plurality of heterocyclic rings and are useful in biological applications and as stabilizers.
