Regioselective and Versatile Synthesis of Indoles via Intramolecular Friedel–Crafts Heteroannulation of Enaminones
(2012-11-25)
A new approach is described for the synthesis of substituted
indoles 5, through an intramolecular and regioselective
Friedel–Crafts cyclization of enaminones 6a–h catalyzed by Lewis
acids. Compounds 6 were prepared from ...
Droplet counter-current chromatography of indole alkaloids from Tabernaemontana hilariana
(1999-01-01)
This paper reports the separation of the indole alkaloids from the benzene extract of the root barks of Tabernaemontana hilariana (Apocynaceae). The crude alkaloid fraction was fractionated by droplet counter-current ...

The quenching of indolic compounds by monosubstituted benzenes and the photoreaction with chlorobenzene
(Royal Society of Chemistry, 2003-08)
The quenching of the excited singlet of indole and its methyl derivatives by monosubstituted benzenes has been studied in three solvents of different polarities and bimolecular quenching rate constants have been determined. ...
