Synthesis of fused cyclic chromene and alicyclic chromene derivatives from 2-amino-4-[4-(dimethylamino)phenyl]5-oxo-4H,5H-pyrano [3,2-c]chromene-3-carbonitrile

Abstract

Derivatives of fused cyclic chromene and alicyclic chromene were synthesized starting from 2-amino-4-[4-(dimethylamino)phenyl]5-oxo-4H,5H-pyrano [3,2-c]chromene-3-carbonitrile. The structures of the synthesized compounds were elucidated by spectral data : infrared spectra (FT-IR) and 1HNMR.
