Presented is a light-promoted C–C bond forming reaction yielding sulfone and phosphate derivatives at room temperature in the absence of metals or photoredox catalyst. This transformation proceeds in neat conditions through an auto-oxidationmechanism which is maintained through the leaching of trace amounts of O2 as sole green oxidant.

Fosmidomycin is a promising antimalarial drug candidate with a unique chemical structure and a novel mode of action. Chain substituted pivaloyloxymethylester derivatives of Fosmidomycin and its acetyl analogueFR900098 have been synthesized and their in vitro antimalarial activity versus the Chloroquine sensitive strain 3D7 of Plasmodium falciparum has been determined.
Synthesis of an analogue of the bisphosphonate drug Ibandronate for targeted drug-delivery therapeutic strategies

An analogue of the bisphosphonate drug Ibandronate was prepared and coupled via a cleavable ester function to a bromoacetyl linker with specific reactivity for thiol groups. This compound should find useful applications in therapeutic strategies aiming to deliver bisphosphonate drugs specifically to cancer cells making use of proteins as vectors. The specific delivery of bisphosphonates to cancer cells instead of bone, the usual site of accumulation of these cytotoxic drugs, could greatly widen their therapeutic applications.

bis(pivaloyloxymethyl) ester prodrugs of Fosmidomycin and its acetyl analogueFR900098. The 3,4-dichlorobenzyl substituted derivative of Fosmidomycin proved to be about twice as active as the respective Fosmidomycin prodrug, however, less active than the corresponding FR900098 prodrug. Electron donating substituents as well as voluminous substituents led to a significant reduction of activity.
