The purpose of the present invention is to provide a novel compound which has an anti-fungal activity on pathogenic fungi including fungi belonging to the genus
Candida
, the genus
Aspergillus
and the genus
Trichophyton
and is useful as a medicinal agent. A compound represented by formula (I) (wherein A
1
represents a nitrogen atom or a group represented by formula CR
6
; A
2
and A
3
are the same as or different from each other and independently represent a nitrogen atom or a group represented by formula CH; R
1
represents an aryl group which may be substituted by 1 to 5 substituents independently selected from a substituent group (2) or the like; R
2
and R
3
are the same as or different from each other and independently represent a hydrogen atom, a halogen atom, a C
1-6
alkyl group, a C
1-6
haloalkyl group or a C
1-6
alkoxy group; and R
4
and R
5
are the same as or different from each other and independently represent a hydrogen atom, a C
1-6
haloalkyl group, a C
1-6
alkyl group or the like) or a salt thereof is useful as an anti-fungal agent.

The effect of structural change on the biological activity of a series of imidazothiazoles and thiazolobenzimidazoles is described. It was found that compounds with polar substituents at the 2 or 3 position of the ring system are less acutely toxic while maintaining antiinflammatoryactivity. Other structural changes, such as the incorporation of a gem-dimethyl substituent in the 6 position, increase
Chemoselective mono halogenation of β-keto-sulfones using potassium halide and hydrogen peroxide; synthesis of halomethyl sulfones and dihalomethyl sulfones
The synthesis of alpha-halo beta-keto-sulfones using potassium halide and hydrogen peroxide as a chemoselective mono halogenation reagent and the synthesis of alpha, alpha-symmetrical and asymmetrical dihalo beta-keto-sulfones and alpha-halo, alpha-alkyl and beta-keto-sulfones is described. Base induced cleavage of alpha-halo beta-keto-sulfones, alpha,alpha-dihalo beta-keto-sulfones, and alpha-halo, alpha-alkyl beta-keto-sulfones afforded the corresponding halomethyl sulfones, dihalomethyl sulfones and haloalkyl sulfones.
