    Abstract:
    Starting from furfural, 5-hydroxy-3,4-dihalo-2(5H)-furanones and 5-hydroxy-4 chloro-2(5H)-furanone were converted into 3 sublibraries of halogenated 5-alkoxy-2(5H)-furanones. The reactivity of 24 halogenated 5-alkoxy2(5H)-furanones was chemically evaluated by using 4 selected amines for subsequent reactions. The biological evaluation of the pseudo-muco halogen esters resulted in the discovery of a lead structure with potent anti-cancer activity.
