The rhodium-catalyzedhydroformylation-hydrogenation of 1,2-allenyl-phosphineoxides and -phosphonates is reported in this paper. The regioselectivity was well controlled, affording only saturated linear γ-phosphinyl aldehydes under the standard conditions: (carbonyl)tris(triphenylphosphine)-rhodium hydride [RhH(CO)(PPh3)3] (3 mol%), triphenylphosphine (PPh3) (10 mol%), carbon monoxide (CO) (2.4×106 Pa)

in the nonmevalonate pathway of isoprenoid biosynthesis represents a promising strategy for the development of novel antimalarial agents. A small series of reverse hydroxamate‐based fosmidomycin analogues was synthesized and evaluated for their inhibitory activity against the recombinant 1‐deoxy‐D‐xylulose 5‐phosphate reductoisomerases (DXRs) of Escherichia coli and Plasmodium falciparum, as well as

Reverse hydroxamate-based inhibitors of IspC, a key enzyme of the non-mevalonatepathway of isoprenoidbiosynthesis and a validated antimalarialtarget, were synthesized and biologically evaluated. The binding mode of one derivative in complex with EcIspC and a divalent metal ion was clarified by X-ray analysis. Pilot experiments have demonstrated in vivo potential.
