PhI(OAc)2-BF3-OEt2 Mediated Domino Imine Activation, Intramolecular C-C Bond Formation and β-Elimination: New Approach for the synthesis of Fluorenones, Xanthones and Phenanthridines
PhI(OAc)2-BF3-OEt2 mediated domino synthesis of biologically important fluorenones, xanthones and phenanthridines has been developed. The reaction proceeds through imine activation, intramolecular C-C bond formation and β-elimination.
