Abstract

The first examples are presented of Diels-Alder cycloadditions of 2(1H)-pyridones having two electron-withdrawing groups on the ring, with electron deficient dienophiles, and the adducts obtained may act as dienophiles leading to richly functionalized, bridged, and polycyclic azacompounds, under high pressure conditions.
