Abstract: In the presence of NaOAc/HOAc the reaction of 6'- aldehydo(8'-Hor NO2)spiroindolinobenzopyran with 3-methylrhodanine was investigated.It is found that the predominant product is 1,3-bisbenzylidenerhodanine derivative, and its structure was confirmed by quantitative analysis, spectrometries.Besides, intermediate condensation product and Fischer base isolated from the reaction mixture were identified.The reasonable mechanism was proposed.

Key words: Aldehydospiropyran, Rhodanine, Reaction mechanism
