Synthesis of substituted tryptamines and their homologs:
a new aspect in the Fischer reaction
E. P. Zakurdaev, E. S. Balenkova, and V. G. Nenajdenko
A number of cyclic imines and amino ketones were studied as the starting material for
indole synthesis. Amino ketone arylhydrazones are key intermediates undergoing the Fischer
rearrangement; the possibility of the reaction is determined by the structure of an amino
carbonyl compound. A convenient one-step method for the synthesis of indolylalkylamines
allowed tryptamines and their homologs to be obtained in high yields.
