Improvements in the hetero diels-alder reactions of 1-dimethylamino-1- azadienes in the presence of an electrophilic scavenger resin

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.
