Abstrakt: The diastereoselective hetero-Diels−Alder reaction between Danishefsky's diene and chiral aldehydes is catalyzed by chiral chromium−Schiff base complexes. High levels of catalyst control are obtained in several cases, allowing access to all four stereoisomeric products through appropriate choice of aldehyde and catalyst enantiomers.
