A series of (±) 3-hydroxyl-and 2, 3-dihydroxy-2, 3-dihydro-7-oxopyrido [3, 2, 1-de] acridines were synthesized for antitumor evaluation. These agents can be considered as analogues of glyfoline or (±) 1, 2-dihydroxyacronycine derivatives. The key intermediates, 3, 7-dioxopyrido [3, 2, 1-de] acridines (15a, b or 24a, b), for constructing the target compounds were synthesized either from 3-(N, N-diphenylamino) propionic acid (14a, b) by treating with ...
