Abstract

An efficient and convenient synthesis of benzo[a]acridines and indeno[1,2‐b]benzo[f]quinolines was achieved in high yields by the reaction of N‐arylidenenaphthalen‐2‐amine with 1,3‐dicarbonyl compounds catalyzed with triethylbenzylammmonium chloride (TEBAC) in aqueous media. The structures were established by spectroscopic data and further confirmed by X‐ray analysis. This method provides several advantages such as neutral conditions, high yields and simple work‐up procedure. In addition, water was chosen as a green and recyclable solvent.
