Synthesis of Novel 1-Aryl-9H-xanthen-9-ones. Synlett. ISSN 0936-5214. 10, p. 1403-14060936-5214http://hdl.handle.net/10198/6239A novel route for the synthesis of 1-aryl-9H-xanthen-9-ones is reported. This methodology involves the condensation of 2-methylchromone with cinammaldehydes leading to (E,E)-2-(4-arylbuta-1,3-dien-1-yl)-4H-chromen-4-ones. The final step was the electrocyclization and oxidation reactions of the latter compounds, in an one-pot synthesis, giving the desired 1-aryl-9H-xanthen-9-ones.eng1-arylxanthones2-methylchromoneAldol condensationElectrocyclizationOxidationjournal article10.1055/s-0030-12605671437-2096
