Regioselective [4 + 2] Cycloaddition versus Nucleophilic Reactions of N-Arylamino Substituted 1,3-Diaza-1,3-butadienes with Ketenes: Synthesis of Pyrimidinone and Fused Pyrimidinone Derivatives. Part 2.

-A novel synthetic method for substituted pyrimidinones (III) and (VIII) via reaction of the title diazabutadienes with ketenes is described. Transformations of (III) and (VIII) leading to fused pyrimidinones (IV) and (IX) are also reported. -(DEY,
