A novel azabicyclic amino acid was synthesized in both enantiopure
forms. The ring-opening metathesis of methyl N-(tert-butoxycarbonyl)-7-azabicyclo[2.2.1]hept-2-ene-1-carboxylates
was used as a method for accessing a new family of enantiopure proline analogues.
metathesis - bicyclic compounds - heterocycles - amino acids - stereoselective synthesis
