【Abstract】 By the reaction of Rhodanine and β-hydroxy-a-naphthaldehyde in the presence of diethanolamine, the 3,3-dithiobisbenzo(f)-Coumarin(Ⅲ) were prepared. When the compound(Ⅲ) reacts with zine dust in the acetic acid solution, (Ⅲ) can be reduced to the compound(IV), (IV) reacted with various michael acceptors, such as acryloni-trile and methyl acrylate, the expected products(V) and (VI) are obtained.更多还原
