3-Chloroquinoline-2,4-diones react with cyanide ions in dimethyl formamide to give 3-cyanoquinoline-2,4-diones in small yields due to the strong hindrance of the substituent at the C-3 atom. Good yields can be achieved if the substituent at this position

3-Alkyl/aryl-3-hydroxy-1H,3H-quinoline-2,4-diones (2) were transformed into isomeric 3-acyloxy-2,3-dihydro-1H-indol-2-ones (3) by thermally induced molecular rearrangement. All products were characterized by their 1H NMR, 13C NMR, an
