Abstract
3-Substituted 2(1H)-pyridones are produced from reaction of 4-(4-morph olino)-3-pentenone 1 with each of the following carbon acids: cyanoace tamide, malononitrile, cyanothioacetamide, acetylacetamide, benzoylace tonitrile. Reaction of ethyl 3-(4-morpholino)-2-butenoate 2 with cyano acetamide gives the corresponding hydroxypyridone. Pyrimidines are for med by reaction of 1 and of 2 with benzamidine and with S-benzylthio-u rea; in the last case, the eliminated morpholine displaces the benzylt hio group to give the final product.
