A convenient preparation of indoline

Journal of Heterocyclic Chemistry, 1966
AbstractAn efficient method for chemically reducing indole to indoline using zinc dust and 85% phosphoric acid is described. 2, 3‐Dimethylindole, 1,2,3, 4‐tetrahydrocarbazole and N‐methyl‐l,2,3,4‐tetrahydrocarbazole are also reduced to the corresponding dihydroindoles in somewhat lower yields. Unlike earlier acid‐metal reductions of indole little or no

New condensed indoline bis-spiropyrans

Chemistry of Heterocyclic Compounds, 2011
The synthesis of new condensed indoline bis-spiropyrans from isomeric hexamethyldihydroindolo-[4,5-e]-and -[7,6-g]indoles, and also from hexamethyldihydrobenzo[e]pyrrolo[3,2-g]indole in three stages has been generalized. By condensation of the isomeric bis-analogs of Fischer's bases obtained at the second stage with salicylic aldehydes, the following ...

[Anticonvulsant effects of indoline derivatives].

Die Pharmazie, 1983
The anticonvulsant activities of several indoline derivatives were tested in mice using the pentetrazole (PTZ) and electroshock seizure model. Furthermore, the toxicity and the influence on hexobarbitone anaesthesia were determined. 2-oxoindoline--the most potent anticonvulsant compound--shows a characteristic modification of PTZ-induced seizures ...
