摘要：

Diels-Alder reaction of 1-methyl-2(1H)-pyridones (Ia-d) having a phenyl group at 3,4,5, and 6 position with N-phenylmaleimide (II) under 10 kbar at 110 °C for 72 h gave a mixture of the endo and exo adducts (IIIa-d and IVa-d) in good yields, some of which were unobtainable under atmospheric pressure conditions. © 1990.
