In the first method, the xanthone moiety is built by Diels\u2013Alder reaction of the referred unsaturated chromones with <jats:italic>N<\/jats:italic>\u2010methylmaleimide under microwave irradiation, followed by oxidation of the obtained adducts with DDQ, whereas the 1,2,3\u2010triazole ring results from the cycloaddition reaction of the acetylene moiety with sodium azide. The second strategy first involves the cycloaddition reaction with sodium azide to provide the 1,2,3\u2010triazole ring, followed by methylation of the triazole NH group prior to Diels\u2013Alder reaction with <jats:italic>N<\/jats:italic>\u2010methylmaleimide.
