A new synthetic procedure of 1-alkyl(aryl)-1H-4-methylimidazole N 3 -oxide derivatives by cyclocondensation of α-amine-oximes and orthoesters was studied. Low yields in the cyclization process were the result of predominant Z-stereoisomer around the oxime moiety of α-amineoxime reactants. Different attempts to improve these yields were assayed, mild conditions being those that produce the best results

zole‐2‐carboxylate, displayed activity on both protozoa. Lipophilicity and redox potential were experimentally determined in order to study the relationship with activity of the compounds. These properties are well related with the observed bioactivity. Imidazole and benzimidazole N‐oxide derivatives are becoming leaders for further chemical modifications and advanced biological studies.
