Demethoxyerythratidinone (10), one of the simplest of the erythrina alkaloids, was isolated in 1973 by Barton et al. from Erythrina lithosperma [14]. A concise approach to such Erythrina alkaloids using a disfavored 5-endo-trig radical cyclization mediated by nickel powder was described by Zard and coworkers [15]. A-Alkenyl trichloroacetamide 7 was... [Pg.575]

New benzylisoquinoline alkaloids are (+ )-iV-norprotosinomenine (14), found in Erythrina lithosperma Blume (Leguminosae), and A-methylpalaudinium chloride (15), isolated from Thalictrum polygamum Muhl. (Ranunculaceae). ... [Pg.119]

Erysodienone (1 R = H), a compound previously unknown in Nature, has been isolated from Erythrina lithosperma. The isolation of erybidine (2) from E. xbidwilli Lindl. is of biogenetic interest. Its structure was determined by spectral studies, Hofmann degradation, and synthesis from erysodienone (1 R = H). This species has been shown previously to elaborate Erythrina alkaloids. [Pg.180]

Benzyl(tetrahydro)isoquinoline alkaloids. B. a. occur especially in various Annonaceae, Lauraceae, Rhamnaceae, Ranunculaceae, Papaveraceae, and Fa-baceae. They are soluble in ethanol, chloroform, ether and poorly soluble in water. Laudanidine is toxic, it acts as a convulsive and respiratory stimulant, laudan-osine is a tetanic toxin, orientaline is the biosynthetic precursor of isothebaine. Pwtosinomenine occurs especially in Erythrina lithosperma (Fabaceae). Papaverine [ 1 -(3,4-dimethoxybenzyl)-6,7-dimethoxyiso-quinoline] acts as a parasympathicolyticum relaxing smooth musculature, it promotes cerebral perfusion (vasodilatation). It is an antiasthmatic and oral anti-spasmodic agent used in the treatment of gastrointestinal spasms LD50 (mouse i. v.) 25 mg/kg. Reticuline is an important precursor of protoberberines, morphi-nans, aporphines, spirobenzylisoquinolines, and rhoeadine alkaloids. [Pg.78]
