Аннотация:
New polyfunctional hydrogenated pyrido[1,2-a]pyrazin- 1-ones were obtained by regioselective recyclization of N-arylitaconimides with alkyl (3-oxopiperazin-2-ylidene)acetates. The supposed cascade reaction pathway involves the Michael addition of the nucleophile to an activated double bond and subsequent intramolecular transamidation of the intermediate with simultaneous recycling.
