The previously undescribed 3-bromo-5-nitro-2-hydroxycinnamaldehyde and a series of its imines were synthesized.It was shown by means of the IR, UV, and PMR spectra that a cyclic 2H-chromene structure is realized in the crystalline state and in solvents with various polarities on passing from the aldehyde, which has a benzenoid structure, to its imines.
