Abstract
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. [ABSTRACT FROM AUTHOR]
