coumarins could be synthesized with many different methods like Perkin reaction, Knoevenagel condensation,
Pechmann condensation, Wittig reaction, Baylis-Hillman reaction,
Claisen rearrangement and Vilsmeier-Haack and Suzuki cross-coupling reaction
Coumarin is prepared by treating the sodium salt of ortho-hydroxybenzqaldehyde with acetic anhydride. It involves other methods which have been developed by Pechmann Claisen, Knoevenagal, Reformatsky reaction and Wittig for the synthesis of pyrone-ring moieties in coumarins.
