Reactions between 1-dimethylamino-1-azadienes and several quinones in the presence of a chloroformyl polystyrene resin proceeded with up to 2.5-fold increase in the isolated yields of the hetero Diels-Alder products, owing to efficient scavenging of dimethylamine liberated from the primary cycloadducts.
