The title compound 2,3,4,9-tetrahydro-9-(3-hydroxy-1,4-dioxo-1H-dihydro-naphthalen-2-yl)-8-methoxy-3,3-dimethyl-1H-xanthen-1-one (5) was obtained by the nucleophilic addition of 2-hydroxy-1,4-naphthoquinone (4) to 2H-chromene derivative 3, which was prepared by the domino three-component coupling reaction of aryne precursor 1 with DMF and the active methylene compound dimedone (2). The one-pot synthesis of the title compound 5 from aryne precursor 1 was also achieved. View Full-Text
