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
Synthesis of novel 3-acyloxy-1,3-dihydro-2H-indol-2-ones and isomeric 4- acyl-1,4-dihydro-3,1-benzoxazin-2-ones: Double rearrangement of 3- hydroxyquinoline-2,4(1H,3H)-diones
