The present invention provides imidazole derivatives of Formula (I-IV), methods of their preparation, pharmaceutical compositions comprising the compounds of Formula (I-IV), and their use in treating human or animal disorders. The compounds of the invention inhibit protein tyrosine phosphatase 1B and thus can be useful for the management, treatment, control, or the adjunct treatment of diseases mediated by PTPase activity. Such diseases include Type I diabetes and Type II diabetes.

it is typically necessary to introduce the boronic acid functional group just prior to its utilization. Overcoming this important limitation, we herein report that air- and chromatographically stable MIDA boronates are compatible with a wide range of common reagents which enables the multistep synthesis of complex boronic acid building blocks from simple B-containing starting materials.
