Fosmidomycin, which acts through inhibition of 1-deoxy-D-xylulose phosphate reductoisomerase (DXR) in the non-mevalonate pathway, represents a valuable recent addition to the armamentarium against uncomplicated malaria. In this paper, we describe the synthesis and biological evaluation of E- and Z-alpha,beta-unsaturated alpha-aryl-substituted analogues of FR900098, a fosmidomycin congener, utilizing

arylation and alkenylation of the alpha-bromoalkenyl phosphonates were investigated with organoboranes and -borates. Arylation was successful with the aryl boronicacids and a palladium catalyst, while alkenylation was found to proceed with alkenyl borates and a nickel catalyst. In addition, an intramolecular Diels-Alder reaction of the diene prepared by the alkenylation afforded the corresponding adduct
