Chiral butenolides are revealed to be good dienophiles in Diels-Alderreactions with cyclopentadiene, affording endo and exo adducts, whose fully characterization is provided. Selectivity of these cycloaddition reactions has been shown to be temperature dependent not as a result of a thermodynamic equilibrium between the isomers, but due to a kinetically controlled process.
