Electron-deficient dienes. 5. An inverse-electron-demand Diels-Alder approach to 2-substituted 4-methoxyxanthones and 3,4-dimethoxyxanthones.
Several 4-methoxyxanthones and 3,4-dimethoxyxanthones were synthesized in good yield via inverse-electron-demand Diels-Alder (IEDDA) driven domino reactions between a series of electron-deficient chromone-fused dienes with 1-(2,2-dimethoxyvinyl)pyrrolidine or tetramethoxyethene, respectively.
