subsequently converted into its zinc seco-derivative. Polymerization gave the corresponding ROMPgel and ROMPsphere (ROMP = ring-opening metathesis polymer) reagents, the latter of which proved efficient as an immobilized catalyst for the sensitized production of singlet oxygen for the purification-minimized parallelsynthesis of endoperoxides and ene adducts.
Trioxaquines are dual molecules that contain a trioxane motif linked to an aminoquinoline entity. Among the different compounds of this series, trioxaquine cis-15 (DU1302 c), prepared from alpha-terpinene, a cheap natural product, showed efficient antimalarialactivity in vitro on both sensitive and resistant strains of Plasmodium falciparum (IC(50)=5-19 nM). A stereochemical description of this stable
