Summary of "A Unified Approach to the Isomeric α-,β-,γ- and δ-Carbolines via their 6,7,8,9-Tetrahydro-counterparts."

A cross-coupling/reductive cyclisation protocol has been employed in a unified approach to all four carbolines. So, for example, the 2-nitropyridine 8, which is readily prepared through an efficient palladium-catalyzed Ullmann cross-coupling reaction, is reductively cyclized under conventional conditions to give 6.7,8,9-tetrahydro-α-carboline (9) that is itself readily aromatized to give α-carboline (1).

Medical and Biotech [MESH] Definitions

A selective D1 dopamine receptor agonist used primarily as a research tool.

Any situation where an animal or human is trained to respond differentially to two stimuli (e.g., approach and avoidance) under reward and punishment conditions and subsequently trained under reversed reward values (i.e., the approach which was previously rewarded is punished and vice versa).

Brief therapeutic approach which is ameliorative rather than curative of acute psychiatric emergencies. Used in contexts such as emergency rooms of psychiatric or general hospitals, or in the home or place of crisis occurrence, this treatment approach focuses on interpersonal and intrapsychic factors and environmental modification. (APA Thesaurus of Psychological Index Terms, 7th ed)

A group of pyrido-indole compounds. Included are any points of fusion of pyridine with the five-membered ring of indole and any derivatives of these compounds. These are similar to CARBAZOLES which are benzo-indoles.

Compounds formed by condensation of secologanin with tryptamine resulting in a tetrahydro-beta-carboline which is processed further to a number of bioactive compounds. These are especially found in plants of the APOCYNACEAE; LOGANIACEAE; and RUBIACEAE families.
