Abstract

stereochemistry stereochemistry (general, optical resolution) O 0030 -031Enantioselective Diels-Alder Reactions:Novel Constrained Bis(oxazoline) Ligand-Metal Triflate Catalysts.-Five chiral ligands, each bearing a bicyclic backbone, are prepared and examined in Mg(OTf) 2 -, Zn(OTf) 2 -, and Cu(OTf) 2 -catalyzed Diels-Alder reactions. A non-C 2 -symmetric bis(oxazoline) bearing a meso backbone was among the most efficient ligands examined. -(TAKACS, J. M.; QUINCY, D. A.; SHAY, W.; JONES, B. E.; ROSS, C.
