Abstract: (S)-3,4-dibromo-5-methoxy-2(5H)-furanone(4) was synthesized by oxidation, etherification and recrystallization, using furfural as the starting material. (S)-3-bromo-5-methoxy-4-(piperazin-1-yl)-2(5H)-furanone(5) was obtained by Michael addition-elimination reactions of 4 with piperazidine. Seven novel 2(5H)-furanone derivatives(7a~7g) containing piperazine-sulfonamide were synthesized by sulfonylation reaction of 5 with substituted sulfochlorides. The structures were characterized by 1H NMR, 13C NMR, IR and HR-MS. The anti-tumor activities against human cervical cancer Hela cell lines were evaluated by MTT method. The results showed that 7a~7g exhibited good inhibition. The IC50 of (S)-N-【4-{[4-(4-bromo-2-methoxy-5-oxo-2,5-dihydrofuran-3-yl)piperazin-1-yl]sulfonyl}phenyl】acetamide(7f) was 0.03 μM(24 h).
