Copper(II)-Bis(oxazoline) Catalyzed Asymmetric Diels-Alder Reaction with a'-Arylsulfonyl Enones as Dienophiles.

[摘要]：Derivatives, and Condensed Benzenoid Compounds) Section a'-Arylsulfonyl enones are efficient bidentate dienophiles for the Cu(II)-bis(oxazoline) catalyzed enantioselective Diels-Alder reaction with a no. of dienes, affording the corresponding products, e.g. I, with good to high enantiomeric excesses. The resulting products can be alkylated and the sulfone removed, so a'-arylsulfonyl enones can be regarded as surrogates of simple monodentate enones, which are poor dienophiles with this catalytic system.
