Diethyl malonate adds to a variety of quinone monoacetals in a Michael reaction; acid- catalyzed loss of methanol and enolization converts the adducts to hydroquinone monoethers substituted ortho to the alkoxy substituent. The same sequence applied to ethyl acetoacetate results in substituted benzo-or naphthofurans.
