features of geiparvarin (1) that account for its cytostatic activity in vitro, a series of geiparvarin analogues (4a-g) modified in the 3(2H)-furanone moiety have been designed and synthesized. The preparation of 4a-g was achieved through a new approach to the 3(2H)-furanone ring based on the elaboration of isoxazole derivatives. Among these synthetic analogues, 4b, the 5-methyl-5-ethyl derivative, proved
