Azomethyne ylides, generated from cyanomethylamino silanes and excess silver fluoride, undergo cycloaddition with quinones to give, after oxidation in situ, quinonoid isoindoles.This reaction provides the key step for a short, high yield synthesis of the
Regiospecific Nucleophilic Aromatic Substitution: Conjugate Addition of Active Methylene Compounds to Quinone Monoacetals and Aromatization of the Adducts
Parker, Kathlyn A.,Kang, Suck-Ku
, p. 1218 - 1224 (2007/10/02)
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
