2-Pyridinecarboxaldehyde and 2-quinolinecarboxaldehyde undergo rapid, tandem aldol-Michael reactions with the lithium, sodium, and potassium enolates of acetophenone at room temperature to give high yields of 3-(2-pyridinyl)-1-phenyl-2-propenone and 3-(2-quinolyl)-1-phenyl-2-propenone, respectively. The aldol condensation product can be obtained in high yield when pyridine is added to the reaction mixture. (C) 1998 Published by Elsevier Science Ltd. All rights reserved.
