We herein reported the utility of 3-(3-(dimethylamino) acryloyl)-2H-chromen-2-one (2), as a
versatile precursor for the synthesis of some new azole systems of possible biological …

The chromane core is widely represented in nature being part of a wide array of secondary
metabolites of plant, fungal, and bacterial origin. In this paper an improved method for the …

Chromene are oxygen-containing heterocycles, abundantly found in nature in the form of
flavone, flavones, flavanones, catechins, anthocyanins and collectively known as flavonoids …

Abstract In this study, 7-Ethyl-6-chlor-2-methyl chromone and 7-Ethyl-6-chlorflavone
