functionalization of aliphatic molecules remains a challenge in organic synthesis. While radical chain halogenation reactions provide efficient access to many halogenated molecules, the use of typical protocols for the selective halogenation of electron‐deficient and strained aliphatic molecules is rare. Herein, we report selective C−H chlorination and fluorination reactions promoted by an electron‐deficient

[Problem] To provide a compound which may be used in treating diseases in which 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) is concerned, especially diabetes and insulin resistance.
[Means for Solution] It was found that a triazole derivative or a pharmaceutically acceptable salt thereof, in which the 3-position of triazole ring is substituted with a trisubstituted methyl group and the 5-position is substituted with a lower alkyl, cycloalkyl or the like, has a strong 11β-HSD1-inhibitory activity. In addition, since the triazole derivative of the present invention shows excellent blood glucose-lowering action, it may be used in the treatment of diabetes and insulin resistance.
