Ethyl 3-aryl-2-(perfiuoroalkanesulfonyl)propenoates were prepared by the Knoevenagel reaction from various aldehydes and ethyl (trifluoromethanesulfonyl)acetate or ethyl (nonafluorobutanesulfonyl)acetate. These deactivated olefins were used in Dials-Alder

Ethyl (nonafluorobutyl)sulfonylacetate (2) reacts stereoselectively with substituted benzaldehydes 3 affording (E)-3-aryl-2-(nonafluorobutyl)sulfonyl-2-propenoates (E)-4, which are good dienophiles. The addition to cyclopentadiene yields exclusively the e
