The annulation of stilbene compounds were studied. Phenanthrene derivates-interme diates of tylophorine were synthesized by annulation from-2,3-bis(3,4-dimethoxyphen yl)acrylic acid and-2,3-bis(3,4-dimethoxyphenyl) acrylonitrile with phenyliodine diace tate as a friendly and high efficient catalyzer.The route was first reported, whose application foreground would be promising.The catalyzer will be used to study of synthesi- zing a series of new phenanthrenes.
