Ketene-S,N-acetals as Synthons for Heterocycles New Synthesis of Pyrimidinones
Ketene-S,N-acetals of type 1, 2 reacted with isocyanates to 5-cyano-uracils 3 and 5-cyano-pyrimidin-2-ones 4,5.Reaction of these with N nucleophiles was investigated furnishing 6-amino-pyrimidinones 6 as well as condensed pyrimidin-2-ones 7-10 and 13.Cyan
