Synthesis of 4-(3-Hydroxyalkyl)pyrimidines by Ring Transformation Reactions of 2-Alkylidenetetrahydrofurans with Amidines.

Domino reactions of amidines with 2-alkylidenetetrahydrofurans, prepared by cyclization of 1,3-dicarbonyl dianions or 1,3-bis-silyl enol ethers with various dielectrophiles, provided an efficient access to 4-(3-hydroxyalkyl)pyrimidines.
