Synthesis of novel quinolines using TsOH/ionic liquid under microwave
In this work, 3-haloacetyl-4-methylquinolines were synthesized from the reaction of 4-alkoxy-3-alken-2-ones [R¹C(O)CH=C(R²)OCH3, where R¹ = CF3, CCl3, CHCl2, CF2Cl, CF2CF3 and R² = Me, Et, Pr, Bu, i-Bu and i-Pe] and 2-aminoacetophenone. The reaction was performed in ionic liquid and 4-toluene sulfonic acid under microwave irradiation. Results showed that the catalytic method was effective. Products were formed in a short time (10-20 min) and presented good yields (70-91%).
