SYNTHESIS OF PYRIDONE-SUBSTITUTED FURAN-2(5H)-ONES AND THEIR INTRAMOLECULAR CYCLIZATION TO AFFORD FURO[3,4-f]ISOQUINOLINES

Abstract
Synthetic approach toward pyridone-substituted furan-2(5H)-ones has been described. Intramolecular cyclization of these compounds leads to novel 7-substituted furo[3,4-f]isoquinolines in moderate to high yields.
