A convenient procedure has been developed for the synthesis of heteroaryl, aryl and alkyl 14-[H]-dibenzo [a,j] xanthenes by one-pot condensation of β-naphthol with heteroaryl, aryl and alkyl aldehydes in the presence of CBr4, under solvent free conditions in very good yields. The catalyst is readily available and is inexpensive to promote the synthesis of xanthenes.
Keywords: Xanthenes, aldehydes, β-naphthol, CBr4, one-pot condensation, metal free conditions
