AsymmetricheteroDiels-Alderreactions 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 heteroDiels-Alder product in 72% enantiomeric excess and 70% isolated yield.
