The reaction of nucleophilic phosphacumulene ylides with visnaginone and khellinone afforded the corresponding phosphanylidene and furochromene derivatives. Moreover, pyranochromenes were obtained from the reaction of chromene carbaldehydes with phosphacumulenes. On the other hand, the phosphanylidene-cyclobutylidenes and their dimers were produced from the reaction of furochromene carbaldehydes with the same phosphonium reagents.
The synthesis and chemistry of functionalized furochromones.4. Addition of nitronate anions to 3-bromochromone and 6-bromofurochromone. An expedient route to furo(3',2':6,7)-benzopyrano(2,3-d)-isoxazolones and chromono(2,3-d)isoxazolones

Addition of nitronate anions to 3-bromochromone 1 and 6-bromofurochoromone 2 results in the efficient generation of 3-hydroxy-2-(1-(hydroxyimino)alkyl,aryl or carboalkoxy) substituted chromones and the corresponding 6,7-disubstituted furochromones. These
