Abstract

The (4 Z, 10 2, 15Ej-2,3-dihydrobilindione 4, along with the fully unsaturated (E, 2, Z)-analogue 8, has been prepared from the corresponding (Z, Z, Z)-isomer by a variation of Falk's method (Falk et ul., 1980). The photochemical and acid-catalyzed back-reactions have been studied by UV-vis and 'H-NMR spectroscopy.
