 Title    Simple Syntheses of 3-Substituted Indoles and their Application for High Yield 14 C-Labelling  
 Abstract    Methods are described which allow the synthesis of several plant indole alkaloids and their metabolites at different scales. Compounds synthesized include gramine (1) (3-di-methylaminomethylindole) which is directly derived from indole, while its biosynthetic precursors 3-aminomethylindole (3) and 3-methylaminomethylindole (2) as well as indole-3-carboxylic acid (7) are synthesized via indole-3-aldehyde (6). Slight changes of the experimental conditions allow syntheses with high yields not only at the molar but also at the /imolar level. This is extremely useful when isotope labelled compounds of high specific radioactivity are required for studies of plant metabolism.
