The 1,3-dipolar cycloaddition between N-acryloyl-oxazolidinone and diphenyl nitrone is catalyzed by chiral catalysts derived from bis(oxazoline) (R)-7 and Mg(II) perchlorate or triflate. In addition to complete regioselectivity, the endo cycloadduct can be obtained with up to 86% ee. The stereochemi

Asymmetric hetero-Diels-Alder reactions of glyoxylate esters and Danishefsky's diene catalyzed by various chiral bis(oxazoline)-lanthanide complexes afforded the corresponding aldol adducts, which upon treatment with trifluoroacetic acid, furnished the hetero-Diels-Alder product in up to 77% enantio
