Abstract
Methyl 2-benzoylamino-3-dimethylaminopropenoate (6) reacts with heterocyclic compounds containing an active methylene group or potential methylene group in the ring system, such as barbituric acid derivatives 1 and 2, pyrazolones 3 and 4, and resorcinol, in acetic acid to afford the corresponding benzoylamino substituted pyranopyrimidinones 7 and 8, pyranopyrazolones 9 and 10, and 2H-1-benzopyranone 11. The method represents a novel procedure for the preparation of condensed pyranones.
