Rhodium-catalyzed olefination of aryl tetrazoles via direct C-H bond activation
Rh(III)-catalyzed direct olefination reaction via aromatic C-H bond activation is described using tetrazole as the directing group. This reaction provides a straightforward way for the synthesis of ortho-alkenyl aryl tetrazoles. Various functional groups tolerate the reaction conditions and afford the corresponding products in moderate to excellent yields.
Ruthenium-Catalyzed meta-Selective C?H Nitration of Biologically Important Aryltetrazoles
The first example of tetrazole-directed meta-selective C?H nitration is described. This transformation provided a straightforward approach for the synthesis of biologically important m-nitroaryltetrazoles in moderate to excellent yields with good functional group compatibility. In addition, new metallo-β-lactamase inhibitors were obtained by further transformation of the synthesized m-nitroaryltetrazoles. (Figure presented.).
