A photochemical route to benzo[a]acridines
Jayabalan,Shanmugam
, p. 217 - 220 (2007/10/02)
A facile synthesis of benzo[a]acridines based on photochemical transformation of 4-hydroxy-2-(2-phenylethenyl)quinolines is reported. The precursor is readily obtained by condensation of a 4-hydroxy-2-methylquinoline derivative with an aryl aldehyde.
