Abstract
The imidazole 4–6 and pyrimidine derivatives 8–11 containing chromone moiety have been obtained through reactions of thiosemicarbazones 1a-c with some electrophiles in basic media. Compound 12 was also used as a precursor for preparation of some novel 1-[(4-oxo-4H-chromen-3-ylmethylene)amino] [1,3,5]triazine derivatives 13–16. The formulations of all new products were verified based on their elemental and spectral analysis.
