A range of qinghaosu (artemisinin) analogues were synthesized from modified dihydroqinghao acid/aldehyde using dark singlet oxygen to trigger off the key step of the trioxane formation. The newly accessed 1,2,4-trioxanes featured a side chain extended from the carbon corresponding to the lactone carbonyl group of qinghaosu through a stable carbon-carbon single bond instead of an acetal oxygen-carbon bond in most similar analogues in the literature. Biotin and various amines were also connected to the qinghaosu core, respectively, through such a linear tether in efforts to develop hybrids and potentially useful probes in search of the in vivo targets.
