## Abstract The __DielsAlder__ reaction of 1,4‐benzoquinone with 1,3‐dienes catalyzed by __Mikami__'s [Ti{(__S__)‐binol(2−)}Cl~2~] complex (binol=[1,1′‐binaphthalene]‐2,2′‐diol) gives cycloadducts in good yield and in high enantiomer excess. A model is proposed to explain the observed absolute con
