The metabotropic glutamate receptor subtype 5 has evolved into a promising target for the treatment of various diseases of the central nervous system, such as Fragile X and L-DOPA induced dyskinesia. One of the most advanced clinical compound is Novartis' AFQ-056 (Mavoglurant), which served us as a template for a scaffold hopping approach, generating a structurally diverse set of potent analogs. Both the limited aqueous solubility and the relatively poor metabolic stability of AFQ-056 were improved with hexahydrocyclopenta[c]pyrrole derivative 54a, which proved to be a valuable candidate for further development.

On treatment with acid the spirocyclic ketoamine 5 undergoes a retro-Mannich reaction followed by recondensation to give the unsaturated imine 8, thus converting the histrionicotoxin carbon skeleton into the pumiliotoxin C skeleton.
