Abstract

Upon irradiation 2-acyl-1,4-quinones (I) underwent a regiospecific condensation to give their dimers, polycyclic compounds (II). An alternative structure (II′), though it is compatible with the NMR spectra of the dimers, was excluded on the basis of converting one of the dimers to a 9,10-phenanthrenequinone derivative (IV). No condensation of I with dienophiles occurred.
