Condensation of fluorosubstituted benzaldehydes with amines and cyclic 1,3-diketones
摘要:
Condensation of fluorosubstituted benzaldehydes with 2-naphthyl or 6-quinolylamine and cyclic beta-diketones (,3-cyclohexanedione, dimedone, and 1,3-indandione) provided new fluoroderivatives of benzo[a]acridine, 4,7-phenanthroline, and benzo[f]indeno[1,2-b]quinoline. Forming in the course of the reaction fluorophenylmethylene-2-naphthyl-(or 6-quinolyl)amines, arylbis(cyclohexane-1,3-dion-2-yl)methanes, and 2-(fluorophenylmethylene)- 1,3-indandiones were isolated.

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 aqueousmedia. The structures were established by spectroscopic data and further confirmed by X-ray analysis. This method provides several advantages
