Abstract: In this paper, we study the condensation of 1,4-diacetylpiperazine-2, 5-dione (2) with aldehydes (3a-n) in the presence of Solid-liquid phase transfer catalytic conditions. Fourteen compounds of (Z)-1-acetyl-3-arylidene(alkylidene)-piperazine-2, 5-dione (4a-n) were synthesized. The configuration of products were discussed.

Key words: 2,5-Piperazinedione, Phase-transfer catalysis, Aldehyde condensation
