Abstract
4-Hydroxy coumarin and its benzo-analogues undergo intramolecular domino Knoevenagel hetero Diels–Alder reactions with O-prenylated aromatic aldehydes and the aliphatic aldehyde, citronellal to afford pyrano fused polycyclic frameworks. A high degree of chemoselectivity was achieved by the application of microwave irradiation.
