Synthesis of novel 2-benzylidenebenzofuran-3(2H)-one derivatives

New derivatives of Z-2-benzylidene-4,6-dimethoxy benzofuran-3(2H)-ones, a main group of Aurones (2-benzylidenebenzofuran-3(2H)-ones), were synthesized by the aldol condensation at first time. Their structures were confirmed by the IR, 1H-NMR and 13C-NMR spectroscopy. Aurones have various biological properties and show fungicide activity, antioxidant activity or antilyshmania.
