Abstract

<p>The preparation of <i>E</i> and <i>Z</i> isomers of 3-ureido-2-cyano-2-propenoates <i>Ia</i> - <i>Id</i> and their base-catalyzed isomerization and cyclization to 5-carboxycytosine derivatives <i>IIa</i> - <i>IIf</i> and 5-cyanouracil derivatives <i>IIIa</i> and <i>IIIb</i> is described. Also described is the preparation of 3-ureido-2-acyl-2-propenoates <i>Va</i> - <i>Vd</i> and their base-catalyzed cyclization to 5-carboxy-2(1<i>H</i>)-pyrimidone derivatives <i>VIa</i> - <i>VIc</i> and 5-acyluracils <i>VIIa</i> - <i>VIIc</i>.
