Efficient Solvent-free Synthesis of 14 H-Dibenzo[a,j] xanthenes Catalyzed by 2-Hydroxy-5-sulfobenzoic Acid
The use of 2-hydroxy-5-sulfobenzoic acid (2-HSBA) to demonstrate the catalyze one-pot condensation of 2-naphthol with various aldehydes under solvent-free conditions is described. This method can be implemented with a wide variety of readily accessible reagents to provide 14H-dibenzo[a,j]xanthenes a...
