N-Alkyl-2-arylmethylideneindoxyls upon exposure to UV or visible light undergo dimerization not to cyclobutane adducts as it has been reported earlier, but to spiropyrano[3,2-b]-pseudoindoxyls with a spiropseudoindoxyl fragment characteristic of many natural alkaloids. The structure of spiropyranopseudoindoxyls was established by NMR spectroscopy and X-ray crystallography.
Reaction of Indol-3(2H)-one Derivatives With Some Active Methylene Compounds

The reaction of substituted (Z)- and (E)-2-arylmethylideneindolin-3(2H)-ones with malononitrile gave the Michael addition products which could be cyclised to the corresponding pyranoindole.Larger molecules such as cyanoacetic acid and ethyl cyanoacetate failed to react.
