| Abstract: | 3-Pyrimidinylcoumarins have been synthesized by interacting 2- and 4-pyrimidinylacetonitriles with substituted salicylic aldehydes, but 9-pyrimidinylpyrano[2,3-f]chromene-4,8-diones were obtained with 8-formyl-7-hydroxychromones. Modification of the corresponding 7-hydroxycoumarins was carried out by acylation and aminomethylation. |
