Alkaloids of the Cactaceae have been studied for the last 120 years. The first half of that period provided the “classic” compounds, after which a large number of usually very similar analogs were isolated or determined with modern methods. Although some unusual synthetic approaches have been developed, their preparation is generally quite straightforward. Their biosynthesis has been studied...
Bufotenine (1, 5-hydroxy- N,N-dimethyltryptamine) was isolated from seeds of Anadenanthera spp., a tree widespread in the Brazilian cerrado, using an efficient acid-base shakeout protocol. The conversion of bufotenine into N,N-dimethyltryptamine (4) and 5-methoxy- N,N-dimethyltryptamine (5) was accomplished through an innovative and short approach featuring the use of novel...
