Synthesis and Biological Evaluation

Abstract Irradiation of 9,10-o-benzeno-4a,9,9a,10-tetrahydro-1,4-anthraquinone 1 and xanthene 2 in benzene gave dihydro-monomer 3 and dihydrodimer 4 of 1 as the final products. The course of the reaction and the structure of the unstable intermediates were investigated by means of 1H-CIDNP technique.
