چکیده مقاله:

1,8-Dioxo-octahydroxanthenes and their derivatives have been used as additives in pH-sensitive fluorescent materials for visualization of biomolecules, dyes compoundsin laser technologies for photodynamic therapy, antagonists for the paralyzing action of zoxazolamine, luminescent sensors, and chiroptical molecular switches [1]. Agricultural bactericide activity, anti-inflammatory effect, anticancer activity, antiviral activity as well as anti-depressant and anti-malarial effects have been reported forseveral functionalized 1,8-dioxo-octahydroxanthene derivatives. They are also important organic intermediates for the synthesis of a plethora of valuable organic molecules on account of the intrinsic reactivity of the 4H-pyran ring in them [2-4]. In the present work, 13 derivatives of 1,8-dioxo-octahydroxanthene was successfully synthesized via three-component reaction of dimedone and various aryl aldehydes in the presence of sulfacetamide as the commercially available catalyst. The structures of the final synthesized heterocyclic compounds were characterized using spectral data (IR, 1H NMR, and 13C NMR) analysis.
