The research focuses on the development of a new series of 6-(40-aryloxy-phenyl)vinyl-1,2,4-trioxanes, specifically compounds 10a–d, 11a–d, and 12a–d, which were synthesized and evaluated for their antimalarial activity against multidrug-resistant Plasmodium yoelii in Swiss mice via the oral route. The purpose of this study was to find structurally simpler, more affordable, and effective synthetic trioxanes that could combat multidrug-resistant malaria. The most active compounds in the series, trioxanes 10b and 10c, demonstrated 100% protection at a dose of 48 mg/kg over four days, comparable to the clinically useful drug β-arteether. The chemicals used in the synthesis process included various aryl alkoxyphenyl vinyl compounds, cyclopentanone, cyclohexanone, 2-adamantanone, and other reagents involved in the photooxygenation and acid-catalyzed condensation steps. The study concluded that cyclopentane-based trioxanes 10b and 10c showed promising activity profiles similar to that of β-arteether, indicating their potential as effective antimalarial agents.
