Abstract

Pyrido[2,1-a]isoquinoline and pyrido[1,2-a]quinoline derivatives have been produced in good yields by the reaction of isoquinoline or quinoline, activated acetylenic compounds, α-halo ketones, and triphenylphosphine in the presence of ZnO nanoparticles (NPs) as an efficient catalyst under solvent-free conditions at room temperature. The reaction workup is easy, and the products can be readily separated from the reaction mixture. ZnO NPs markedly improved the yield of the product. The catalyst showed significant reusable activity.

Key words

pyridoisoquinolines - pyridoquinolines - solvent-free synthesis - dialkyl acetylenedicarboxylates - nanoparticles - zinc oxide

  • 28 ZnO Nanoparticles NaOH (0.44 g) was dissolved in distilled H2O (75 mL) at r.t. Zn(OAc)2·2H2O (0.6 g) was added, and the solution and was heated at 80 °C for 1.5 h. The solution was then cooled to r.t., and the precipitate was collected by filtration and washed several times with distilled H2O and 96% EtOH. The solid ZnO NPs were dried in air at r.t. for 24 h. Pyrido [2,1-a]isoquinolines 5a–f; General Procedure To a stirred mixture of isoquinoline 1 (0.258 g, 2 mmol) and the appropriate activated acetylenic diester 2 (2 mmol) was added a mixture of Ph3P (4; 2 mmol), the appropriate alkyl bromide 3 (2 mmol), and ZnO NPs (10 mol%). The resulting mixture was stirred at r.t. for about 5 h until the reaction was complete (TLC). H2O (15 mL) was poured onto the reaction mixture, and the solids were collected by filtration. The catalyst was separated by washing the solid with EtOAc (2 × 3 mL) and filtering. The EtOAc was evaporated and the residue was washed with Et2O.
