Synthesis of some new fluorine containing 3-dialkylaminomethyl indoles, 3-indolylglyoxamides and tryptamines

Synthese einiger neuer Fluor enthaltender 3-Dialkylaminomethyl-indole, 3-Indolylglyoxamine und Tryptamine


Several new 2-(fluoroaryl)-3-dialkylaminomethylindoles, 3-acetyl-2-(fluoroaryl)-indoles, 2-(fluoroaryl)-3-indolylglyoxamides and corresponding tryptamines have been prepared as possible psychopharmacological agents. 2-(Fluoroaryl)-indoles have been synthesized by theFischer indole synthesis. 2-(Fluoroaryl)-indoles on treatment with oxalyl chloride and subsequent reaction with amines, gave 2-(fluoroaryl)-3-indolylglyoxamides. Some of these indolylglyoxamides were reducted with lithium aluminium hydride, to the corresponding tryptamines. 2-(Fluoroaryl)-indoles when subjected toMannich reaction afforded 3-dialkylaminomethyl-2-(fluoroaryl)-indoles. All these new compounds have been characterized by IR spectral studies.


Die Titelverbindungen wurden wegen eventueller psychopharmakologischer Wirksamkeit synthetisiert. 2-(Fluoraryl)-indole wurden nach derFischer schen Indolsynthese hergestellt, 2-(Fluoraryl)-3-indolyl-glyoxamide durch Behandlung mit Oxalylchlorid und Aminen. Reduktion ergab die entsprechenden Tryptamine. Außerdem wurden die 2-(Fluoraryl)-indole mittelsMannich-Reaktion in 3-Dialkylaminomethyl-2-(fluoraryl)-indole übergeführt. Die Infrarotspektren aller neuen Verbindungen wurden untersucht.
