A new methodology for the synthesis of flavonols is described. The key step is a base-mediated cyclization-isomerization-elimination reaction which results in the formation of flavonols. Using this strategy, three flavonols are synthesized and characterized. flavonols - base-mediated cyclization - 3,5,6,7-tetramethoxyflavone - LDA
