Abstract
During thermolysis 6-aryl-2,2-dimethyl-1,3-dioxin-4-ones react with al pha-mono- and alpha,alpha-dioxoketene aminals to yield 3-acetyl-6-aryl -2-benzoylamino-4-pyridones or 6-aryl-2-methylene-4-pyrimidones, respe ctively. A scheme of the formation of pyrido[2,3-d]pyrimidines from di oxinones and 1-amino-1-benzoylamino-1-bytene-3-one has been suggested.
