Préparation et évaluation antiparasitaire de nouveaux imidazoles portant le motif dioxane ou hexahydropyrimidine
摘要:
5-Nitro-1,3-dioxane and 5-nitrohexahydropyrimidine salts are found to be suitable nucleophiles for S(RN)1 reactions. From C-alkylation products, base-promoted nitrous acid elimination and acid-catalyzed cleavage of the resulting acetals afford new compounds. Only the imidazole derivatives exhibit significant amoebicide and trichomonacide activities. Structure-activity relationships are discussed.

The reaction of 3-chloro-2-chloromethyl-1-(1-methyl-5-nitroimidazol-2-yl)prop-1-ene with 2-nitropropane anion which gives three products is shown to proceed by an initial S(RN)1 mechanism followed by another S(RN)1 leading to the bis-C-alkylation product or S(N)2 or S(N)2' and Michael reactions.
