Synthesis and antioxidant properties of novel quinoline–chalcogenium compounds
摘要:
Herein we describe our results on the synthesis and antioxidant properties of 4-arylchalcogenyl-7-chloroquinolines. This new class of compounds has been synthesized in high yields by the reaction of 4,7-dichloroquinoline with diaryl dichalcogenides using KOH as base, DMSO as solvent at 100 C under air atmosphere and tolerates a range of substituents in the arylchalcogenyl moiety. The obtained compounds 3a and 3j were screened for in vitro antioxidant activity and the results demonstrated that compound 3j presented a potent antioxidant effect when compared to compound 3a.
