Synthesis of some cyclic ketones which include (2E)-3-(2-chloroquinolin-3-yl)-l-phenyl-2-propen-1-one, (2E)-3-(2-Chloro-6-methylquinolin-3-yl)-1-phenyl-2-propen-1-one, (2E)-3-(2,7-Dichloroquinolin-3-yl)-1-phenyl-2-propen-1-one, (2E)-3-(2-Chloro-6-methoxyquinolin-3-yl)-1-phenyl-2-propen-1-one, 2E)-3-(6-Bromo-2-chloroquinolin-3-yl)-1-phenyl-2-propen-1-one were achieved through the condensation of 3-fomylquinolines with acetophenone and 3-acetyl-4-hydroxyquinolin-2(1H)-one with different heterocyclic aldehydes. The synthesized ketones have been screened for insect attractant activities and insecticidal effect against houseflies. All the ketones have shown significant insect attractant properties.
