Cross coupling of bromo sydnones: development of a flexible route toward functionalized pyrazoles.
The application of a Suzuki cross coupling approach to a range of C-4 substituted sydnones from a 4-bromosydnone is described. Moreover, the potential of this approach to prepare a diverse range of pyrazoles is demonstrated.
