Heterogeneous catalyst: Amberlyst-15 catalyzes the synthesis of 14-substituted-14H-dibenzo[a,j]xanthenes under solvent-free conditions
Ko, Shengkai,Yao, Ching-Fa
, p. 8827 - 8829 (2006)
A one-pot condensation of β-naphthol with aldehydes in the presence of Amberlyst-15 to give 14-substituted-14H-dibenzo[a,j]xanthenes under solvent-free condition is described.
Camphor-10-sulfonic acid catalyzed condensation of 2-naphthol with aromatic/aliphatic aldehydes to 14-aryl/alkyl-14H-dibenzo[a,j]xanthenes
Kundu, Kshama,Nayak, Sandip K.
, p. 1051 - 1058 (2015/02/05)
The (±)-camphor-10-sulfonic acid (CSA) catalyzed condensation of 2-naphthol with both aliphatic/aromatic aldehydes at 80 °C yielded 14-alkyl/ /aryldibenzoxanthenes as the sole products in high yields. However, the same condensation with benzaldehyde at 25

scheme or table, p. 20 - 24 (2010/10/03)
Libraries of benzoxanthenes, as well as of benzochromenes, were efficiently synthesized via one-pot, three-component reactions of 2-naphthol, aldehydes, and cyclic 1,3-diketones/malononitrile/ethyl cyanoacetate in the presence of catalytic amount of eerie
Perchloric acid-silica (HClO4·SiO2)-catalyzed synthesis of 14-alkyl- or 14-aryl-14H-dibenzo[a,,j]xanthenes and N-[(2-hydroxynaphthalen-1-yl)methyl]amides
