The cycloaddition of spirobutenolide 3 to the homochiral cyclopentadiene 1 at 6.5 kbar leads exclusively to cycloadduct 5 . Subsequent Diels–Alder or Michael additions again favour the cyclohexenone double bond; this perfect chemo‐ regio‐ and face selectivity was employed for a short and efficient approach to the wistarin framework.
