Synthesis and cytotoxic activity against L1210 leukemia of new aminocyclopenta[c]thiophenones.

Synthesis of some new hydroxyaminocyclopenta[c]thiophenones was achieved via halogenation reaction, then formation and finally cleavage of an aziridino ring. The in vitro cytotoxic activity of these compounds was evaluated against L1210 leukemia. The importance of the ketohydroxyethylamino sequence for their activities is discussed.
