Electrochemistry of Natural Products. 7. Oxidative Decarboxylation of Some Tetrahydro-β-carbolinecarboxylic Acids
Bobbitt, James M.,Willis, John P.
, p. 1978 - 1984 (1980)
A series of 1,2,3,4-tetrahydro-β-carboline-1- and -3-carboxylic acids containing various substituents in positions 1, 2, and 3 were oxidized electrochemically.In general, the acids were decarboxylated, and unsaturation was introduced into the C ring.The oxidation appears to take place through the indole ring nitrogen, and possible mechanisms of the reactions are presented.Parallels between the observed reactions and early steps in indole alkaloid biosynthesis are discussed.The oxidative dimerization of tetrahydrocarbazole is reported.

, p. 3541 - 3550 (2011)
A mild and efficient one-pot reaction for the synthesis of 1-substituted βcarboline derivatives via the Minisci reaction has been developed with good yields and selectivity. In addition, the mechanism of the 1-substituted βcarboline derivatives by means of the nucleophilic radical is described.

The rise of the resistance of the malaria parasite to the currently approved therapy urges the discovery and development of new efficient agents. Previously we have demonstrated that harmicines, hybrid compounds composed from β-carboline alkaloid harmine
First total synthesis of the β-carboline alkaloids trigonostemine A, trigonostemine B and a new synthesis of pityriacitrin and hyrtiosulawesine

The total synthesis of four natural products, trigonostemine A, trigonostemine B, pityriacitrin, and hyrtiosulawesine was accomplished. The key intermediates, variously substituted 1-formyl-β-carbolines, were prepared in five steps via a novel synthetic approach using readily available starting materials. These formyl derivatives were then further transformed, providing a general route for the synthesis of the four title alkaloids. The method reported herein represents the first total synthesis of the two trigonostemines and a new pathway to pityriacitrin and hyrtiosulawesine.
Studies on the Constituents of Picrasma quassioides BENNET. III. The Alkaloidal Constituents
Ohmoto, Taichi,Koike, Kazuo
, p. 3579 - 3583 (2007/10/02)
A new β-carboline alkaloid, named picrasidine E(I), was isolated from the wood of Picrasma quassioides BENNET (Simaroubaceae) together with seven known alkaloids, 1-methoxycarbonyl-β-carboline (II), 1-ethoxycarbonyl-β-carboline (III), 1-formyl-β-carboline (IV), 1-hydroxymethyl-β-carboline (V), β-carboline-1-propionic acid (VI), 4,5-dimethoxy-canthin-6-one (VII), and 5-hydroxy-4-methoxycanthin-6-one (VIII).These structures were elucidated on the basis of spectroscopic and chemical evidence.Keywords - Picrasma quassioides; Simaroubaceae; wood; picrasidine E; β-carboline type alkaloid; canthin-6-one type alkaloid.

, (2008/06/13)
1-Substituted-9H-pyrido[3,4-b]indole derivatives, which are further optionally substituted in the 3- or 4-position, are inhibitors of xanthine-oxidase. A representative embodiment is 1-formyl-4-hydroxy-9H-pyrido[3,4-b]indole which can be prepared through
