Abstract

The reaction of substituted 3‑cinnamoyl-4-hydroxycoumarins with pyridinium salts of various bromomethyl ketones gives the corresponding 4‑hydroxy‑3‑pyridylcoumarins. The use of microwave radiation decreases the time required and improves the yield of this reaction. The products obtained do not display solvatochromic properties or photochemical activity.
