designed and synthesized. Their anti-tumor activity in vitro was evaluated. Among them compound I-14 exhibited broad spectrum anti-cancer activity against five human cancer cell lines with IC50 <30 μM. Structure–activity relationship analysis showed that the introduction of dithiocarbamate side chains on the C-3 position of butenolide was crucial for anti-tumor activity.

The synthesis of 3-(1-hydroxyalkyl)-5H-furan-2-ones; 4a–c, is reported. The reaction of lactones 4a and 4b with bromine under typical ionic bromination conditions gives as major product the unexpected substitution of the allylic hydroxyl group. Only the less hindered double bond in 4c gives some proportion of the normal addition product. The bromine chloride addition to 4c proceeds with 55% yield,
