Abstract
AbstractA simple and efficient procedure for the synthesis of 14-aryl-14H-dibenzo[a,j]xanthene derivatives through one-pot condensation of 2-naphthol with aryl aldehydes in the presence of niobium pentachloride is described. The reactions were carried out using 25 mole % of NbCl5, at ambient temperature, and in acceptable reaction times, affording excellent yields of the products.
