Preparation of enantiopure norbornane ligands bearing both (2S,3S)-bis(phosphinomethyl) and 7-syn-oxygen functional groups and an application to rhodium-catalyzed asymmetric hydrogenation.

Enantiopure bicyclo[2.2.1]heptane derivatives having both (2S,3S)-bis[(diphenylphosphino)methyl] and 7-syn-oxygen functional groups were synthesized by using diastereoselective Diels-Alder reaction of di-(1R)-menthyl fumarate and 5-trimethylsilylcyclopentadiene followed by silver-promoted stereospecific frame rearrangement of a bromolactone intermediate. Rhodium-catalyzed asymmetric hydrogenations were carried out using the diphosphines as a chiral ligand.[1]
