摘要
A facile synthesis of unreported pyridine-2,6-diylbis(benzofuran-2-ylmethanone) derivatives was described. The synthesis mainly relied on the ultrasound-assisted Rap-Stoermer reaction of 1,1'-(pyridine-2,6-diyl)bis(2-bromoethanone) with a variety of salicylaldehydes in MeCN at the presence of PEG-400. This procedure offered easy access to construct new prototypes containing methanone linker between the benzo(naphtho)furan ring and pyridine moiety at 2,6-position in a short reaction time and mild conditions with good yields. Compound structures were identified by means of H-1(C-13) NMR, IR and elemental analysis.
