C. Bozzo et Md. Pujol, Deoxygenation of 5,12-epoxy-5,12-dihydro-5,12-dimethyl-1,4-benzodioxino[2,3-g]isoquinoline with iron compounds. Synthesis of antitumour agents, SYNLETT, (4), 2000, pp. 550-552
Fe-2(CO)(9) in benzene is effective in removing the oxygen from 5,12-epoxy-
5,12-dihydro-5,12-dimethyl-1,4-benzodioxino[2,3-g]isoquinoline to give 5,12
-dimethyl-1,4-benzodioxino[2,3-g]isoquinoline, an analogue of ellipticine,
a known antitumour agent.(1-2).
