Abstract
A novel approach to the synthesis of spirobicyclic Janovsky complexes is described. The complexes were prepared on silica and polystyrene polymeric supports as well as on a solution-borne poly(carbodiimide) polymer with 100% atom economy. A carbon-centered intramolecular de-aromatizing nucleophilic aromatic substitution ipso-cyclization mechanism describes the synthesis of these spirobicyclics. The molecules were characterized by solution and solid-state 1H and 13C NMR, IR, and MS.
