General description
5-Bromoisatin is a 5-haloisatin. One of the methods reported for its synthesis is by reacting N-halosaccharins with isatin in the presence of SiO2. Its inotropic activity has been studied on rhythmically stimulated papillary muscles of guinea pigs. It is reported to exhibit analgesic and sedative properties at a dose of 0.2g/kg in mice.
Application
5-Bromoisatin may be used in the synthesis of the following:
- N-derivatives of 5-bromoisatin
- N-substituted pyrroles
- linear polyaryleneoxindoles
- 5-bromodioxindole
- cinchoninic acid derivatives
- 3-hydroxyoxindole
- S-benzyldithiocarbazate Schiff Bases
- 5-bromooxindole
- Morita-Baylis-Hillman adducts of isatin derivatives
