✦ Synopsis

Asymmetric hetero-Diels-Alder reactions of glyoxylate esters and Danishefsky's diene catalyzed by various chiral bis(oxazoline)-lanthanide complexes afforded the corresponding aldol adducts, which upon treatment with trifluoroacetic acid, furnished the hetero-Diels-Alder product in up to 77% enantiomeric excess and 73% isolated yield.
