The Fischer base reacts with α-ethyl-5-nitro-, 5-bromo-, and 3,5-dibromo-2-hydroxycinnamaldehydes to give bisindole spirochromans, with 3-bromo-5-nitro-2-hydroxycinnamaldehyde to give a mixture of a spirochroman and monoindole merocyanine, and with 3,5-dinitro-2-hydroxycinnamaldehyde to give only a merocyanine.The monoindole merocyanines obtained do not display a tendency to undergo intramolecular cyclization to give spiro-2H-oxocines.

Disubstituted tryptamines, containing methyl, methoxy, nitro, and amino groups, chlorine, and bromine in benzene ring, were synthetized.The influence of substituents on the course of individual stages of synthesis was noted.
