Metelitsa, O. Lyashik, S. Aldoshin, O. Kozina, N. Volbushko, E. Medyantseva, M. Knyazhanskii, V. Minkin, A. Atovmyan] Previously undescribed fulgides of the indole series, viz., (1-methyl-3-indolylmethylene)- and (1-methyl-3-indolylethylidene) (isopropylidene)succinic anhydride, were synthesized. A Z conformation for (1-methyl-3-indolylmethylene) (isopropylidene)succinic anhydride and an E configuration for (1-methyl-3-indolylethylidene)-(isopropylidene) succinic anhydride were established by electronic and PMR spectroscopy and x-ray diffraction analysis. The photochromic properties of fulgides were observed and investigated. A scheme of photoinduced and thermal transformations of fulgides that includes a step involving Z → E isomerization in the excited state is proposed. An additional photoisomer was recorded by pulse photolysis and fluorescence. Plenum Publishing Corporation, 1990 Metelitsa A.
