Abstract Two types of novel rare earth (RE) complexes were synthesized and used as a chiral Lewis acid catalyst for the hetero-Diels–Alder reaction of carbonyl compounds with the Danishefskys diene under homogeneous conditions. The Y[( R )-H 8 -BNP] 3 ( 3 -Y )-catalyzed reaction of aromatic aldehydes and the Yb[( R )-BNP] 3 ( 1 -Yb )-catalyzed reaction of phenylglyoxylates afforded the corresponding cycloadducts with excellent optical purities (up to 99% ee) in high yields at room temperature. The successful recycling uses of the scandium catalyst ( 3 -Sc ) are also described.
