Abstract

Except from 1,4,9,10‐anthracenetetrols, 9,10‐anthrahydroquinones (derived from the quinones 5a and 18– 21) react with unhindered Michael acceptors such as acrylate, acrylonitrile, acrylaldehyde, and methyl vinyl ketone with addition at C‐9 or C‐10 to yield anthrones. The direction of the addition is mainly influenced by steric factors.
