| 摘要 |
Novel unsaturated derivatives of 1,6-diaza [4,4] spirodilactams having a monovalent unsaturated substituent on each spiro ring nitrogen atom are produced by reaction of an unsaturated amine and a spirodilactam precursor selected from a 4-oxoheptanedioic acid compound or a 1,6-dioxo [4,4] spirodilactone.
