Synthesis new fused and non-fused chromene [I] derivatives derived from 2-amino-4-[4-(dimethylamino)phenyl]-5-oxo-4H,5H-pyrano[3,2-c]chromene-3-carbonitrile
Abstract
A new series of pyrano-chromene and pyrimido pyrano-chromene derivatives were synthesized starting from 2-amino-4-[4-(dimethylamino)phenyl]-5-oxo-4H,5H-pyrano[3,2-c]chromene-3-carbonitrile (5). The structures of the synthesized compounds were elucidated by spectral data.
Key words: Chromenes, Pyrano-chromenes
