(2008). Synthesis and antioxidant activity of new methoxylated di(hetero)arylamines derivatives of thieno[3,2-b]pyridines. In International Conference in Medicinal Chemistry: Interfacing Chemical Biology, Natural Products and Drug Discovery. Angershttp://hdl.handle.net/10198/3708Due to their isosterism with pyrrolopyridines or quinolines, thieno[3,2-b]pyridines have attracted much attention because of their potential biological activity [1]. We have prepared the 6-bromothieno[3,2-b]pyridine 1, following a known method used by us for benzo[b]thiophene compounds [2], as component for palladium-catalyzed Buchwald-Hartwig coupling with methoxylated ani lines. The corresponding di(hetero)arylamines 2a-2d were obtained in good yields and were fully characterized (Scheme 1).engconference object
