The activity of dispiro peroxides against Fasciola hepatica [PDF]
Dispiro 1,2,4-trioxanes and 1,2,4,5-tetraoxanes had superior efficacy against Fasciola hepatica than the corresponding ozonides (1,2,4-trioxolanes). For highest efficacy, spiroadamantane and carboxymethyl substructures were required. Three compounds completely cured F.

Weak base dispiro-1,2,4-trioxolanes: Potent antimalarial ozonides
Thirty weak base 1,2,4-dispiro trioxolanes (secondary ozonides) were synthesized. Amino amide trioxolanes had the best combination of antimalarial and biopharmaceutical properties. Guanidine, aminoxy, and amino acid trioxolanes had poor antimalarial activity. Lipophilic trioxolanes were less stable metabolically than their more polar counterparts.

Stereoselective Synthesis of Novel Dispiro Oxindole-pyrrolothiazole-androsterone Hybrids [PDF]
A facile synthesis of novel dispiro oxindole-pyrrolothiazole-androsterone hybrid heterocycles has been achieved through 1,3-dipolar cycloaddition. The reaction proceeds stereo- and regioselectively, affording a single isomer of the product in excellent yields with the formation of two C–C and one C–N bonds and creation of four new contiguous ...
