Compound having antiparasitic properties are 1,2,4-trioxanes of the formula: (VII) in which: R1 and R2 together with the adjacent carbon atom form a cycloalkyl group which may be interrupted by an oxygen atom; R3 is a hydrogen atom or a hydroxyl group or etherified or esterified hydroxyl group having the exo or the endo configuration, which, when an etherified, esterified or aminated group, may be further functionalized with a phosphate, phosphonate, carbamate or carboxylate group; R4 is an aromatic substituent, optionally substituted with a halogen atom, an alkyl group, a trifluoromethyl group, an alkoxy-alkoxy group or an alkylamino group; and the dotted lines between positions 5 and 6 and positions 6 and 7 indicate that there is present a 5,6or 6,7- double bond.
