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.

Ключевые слова: pyrido[1,2-a]pyrazin-1-ones, N-arylitaconimides, alkyl (3-oxopiperazin-2-ylidene)acetates, recyclization, microwave irradiation.
