Abstract
Asymmetric hetero Diels-Alder reactions of Danishefsky's diene and gly oxylate esters catalyzed by bis(oxazoline)-metal complex afforded the corresponding aldol adduct which upon treatment with trifluoroacetic a cid furnished the hetero Diels-Alder product in 72% enantiomeric exces s and 70% isolated yield.
