Condensation of different cyclic ketones with visnaginone la and khellinone lb afforded spirofurochromanone derivatives 2a-f. Compounds 2a and 2b were readily demethylated to give the compounds 3a and 3b. Nitration of 2b and 2e gave the nitrofurochromonone and quinone derivatives 4 and 5 respectivel
