Description
| - Článek se věnuje štěpení heterocyklických sloučenin v organické syntéza. Diskutuje použití 5-nitroisatinu pro syntézu různých dusíkatých heterocyklů. (cs)
- The reactions of 5-nitroisatine were studied with nucleophiles like heterocyclic amines and alkaline hydroxide . With the use of alkaline hydroxide it was converted into 2-amino-5-nitrophenylglyoxylic acid , with piperidine, morpholine and carbethoxypiperazine to its amides or by oxidation to 5-nitroanthranilic acid . This acid was used for synthesis of 3-hydroxy-6-nitro-2-phenyl-1H-quinolin-4-one . Semicarbazone of 5-nitroisatine was converted to 5-(2-amino-5-nitrophenyl)-2,3,4,5-tetrahydro-1,2,4-triazine-3,5-dione . Cyclocondensation of this compound to afford 8-nitro-2,3-dihydro-5H-[1,2,4]triazino[5,6-b]indol-3-one was unsuccessful.
