Synthesis of 1,6-disubstituted 2,4-pyridinediones from 5-acetoacetyl-2,2- dimethyl-1,3-dioxane-4,6-dione

5-Acetoacetyl-2,2-dimethyl-1,3-dioxane-4,6-dione reacts with aliphatic amines and p-methoxy-aniline to afford the corresponding 5-[3-alkyl(or aryl)amino-2-butenoyl] derivatives. Heating of the latter in boiling toluene gives 86-90% of N-substituted 6-meth
