Synthesis of 14-Fluorophenyl-14H-Dibenzo[a,j]xanthenes and Their Derivatives under Microwave Irradiation and Solvent-free Conditions

Synthesis of 14-Fluorophenyl-14H-Dibenzo[a,j]xanthenes and Their Derivatives under Microwave Irradiation and Solvent-free Conditions

A facile and efficient synthesis of 14-fluorophenyl-14H-dibenzo[a,j]xanthenes has been developed by one-pot condensation of fluorinated benzaldehydes with β-naphthol in the presence of p-TSA·H2O under microwave irradiation and solvent-free conditions. These products are conveniently oxidized to 14-f...

Zusammenfassung:A facile and efficient synthesis of 14-fluorophenyl-14H-dibenzo[a,j]xanthenes has been developed by one-pot condensation of fluorinated benzaldehydes with β-naphthol in the presence of p-TSA·H2O under microwave irradiation and solvent-free conditions. These products are conveniently oxidized to 14-fluorophenyl-14-hydroxydibenzo[a,j]xanthenes by PbO2 in acetic acid in good yields.
