time [4+2]-cycloaddition reactions were carried out between furfuryl vinylethers and typical dienophiles and heterodienes proceeding in uncatalyzed conditions and resulting in previously unknown heterocyclic systems containing either free vinyloxy groups or furfuryl substituents. With maleic anhydride and maleimide furfuryl vinylethers afforded 1-(vinyloxyalkyl)tricyclodec-8-ene-3,5-diones in up to 72%
