- Access to newly functionalized imidazole derivatives: Efficient synthesis of novel 5-amino-2-thioimidazoles using propylphosphonic anhydride (T3P)
-
We describe here an efficient method to synthesize 5-amino-2-thioimidazole compounds by T3P-mediated cyclization of N-acetamidoisothiourea intermediates. The newly functionalized 5-amino-2-thioimidazole compounds are finally obtained in 5 steps from an amine as starting block.

Heterocyclic amide derivatives, of formula (I): wherein —X-Y-Z- is selected from —S—CR4═CR5—, —CR4═CR5—S—, —O—CR4═CR5—, —CR4═CR5—O—, —N═CR4—S—, —S—CR4═N—, —NR6—CR4═CR5— and —CR4═CR5—NR6—; or a pharmaceutically acceptable salt or an in vivo hydrolysable ester thereof; (with provisos); possess glycogen phosphorylase inhibitory activity and accordingly have value in the treatment of disease states associated with increased glycogen phosphorylase activity. Processes for the manufacture of said heterocyclic amide derivatives and pharmaceutical compositions containing them are described.
