Sc[N(SO2C8F17)2]3 catalyzed condensation of β-naphthol and aldehydes in fluorous solvent: One-pot synthesis of 14-substituted-14H-dibenzo[a,j]xanthenes

A facile synthesis of 14-substituted-14H-dibenzo[a,j]xanthenes was proposed by one-pot condensation of β-naphthol with aryl or alkyl aldehydes by using Scandium bis(perfluorooctanesulfonyl)imide complex as catalyst and perfluorodecalin as sole solvent.
