A fast and efficient synthesis of flavanones from cinnamic acids in three steps was developed. First, the cinnamic acids were converted to cinnamoyl chlorides using SOCl2. The acid chlorides were then treated with substituted phenols in BF3¡¤OEt2 to furnish the corresponding chalcones in 42-75% yields. Base-catalyzed cyclization of the chalcones at room temperature afforded the corresponding flavanones in 85-95% yields. The conversion of the cinnamic acid derivatives to corresponding chalcones was found to be sensitive to the position and nature of the substituents on the aromatic rings.
