An iron-catalyzed practical synthesis of 2-trifluoromethylarylimidazoles through condensation of o-arylenediamines and hexafluoroacetylacetone followed by intramolecular addition and C–C bond cleavage in one-pot has been developed. A series of title compounds were obtained with up to 99% yield. This method is quite practical and suitable for scalable preparation due to simple experimental procedure and readily available reagents.

A series of 2-(trifluoromethyl)-1H-benzimidazole derivatives with various 5- and 6-position bioisosteric substituents (-Cl, -F, -CF3, -CN), namely 1-7, were prepared using a short synthetic route. Each analogue was tested in vitro against the protozoa Giardia intestinalis and Trichomonas vaginalis in comparison with albendazole and metronidazole. Several analogues had IC50 values 1 μM against both species, which make them significantly more potent than either standard. Compound 4 [2,5(6)- bis(trifluoromethyl)-1H-benzimidazole], was 14 times more active than albendazole against T.:vaginalis. This compound (4) also showed moderate antimalarial activity against W2 and D6 strains of Plasmodium falciparum (5.98 and 6.12 μM, respectively). Studying further structure activity relationships through the use of bioisosteric substitution in these benzimidazolic derivatives should provide new leads against protozoal and possibly malarial diseases.

2-(Trifluoromethyl)benzimidazole derivatives substituted at the 1-, 5-, and 6-positions have been synthesized and in vitro tested against the protozoa Giardia lamblia, Entamoeba histolytica, and the helminth Trichinella spiralis. Results indicate that all the compounds tested are more active as antiprotozoal agents than Albendazole and Metronidazole. One compound (20) was as active as Albendazole against T. spiralis. These compounds were also tested for their effect on tubulin polymerization and none inhibited tubulin polymerization.

Cyclocondensation of N-(carbotrifluoromethyl)-ortho-arylenediamines leads to a series of 2-trifluoromethylarylimidazoles with good yields on montmorillonite K10 in 'dry media' under microwave irradiation within 2 min in a domestic oven. By conventional heating in the same conditions, no reaction is observed.
