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