AbstractA free radical reaction between 2‐anilino‐1,4‐naphthoquinones and diethyl malonate initiated by manganese (III) acetate is described. This reaction provides a novel method for the synthesis of 5,6,11,12‐tetra‐hydro‐6,11‐dioxo‐benzo[b]acridines. With a meta substituent on the anilino group, this reaction shows poor to high regioselectivity depending on the steric effect of the substituents on the anilino group and malonate.
