title: Catalyst-controlled diastereoselective hetero-Diels-Alder reactions.
abstract: [reaction: see text] 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.
