Regioselective Synthesis of Pyrimidines from Ketene Dithioacetals or Alkoxymethylene Compounds
摘要:
Regioselective cyclizations of the condensation products obtained by the reaction of nitrogen nucleophiles with ketene dithioacetals or alkoxymethylene compounds are reported. Stereoelectronic factors or geometry of the carbon-carbon double bond determine the regioselectivity of heterocyclization processes.
